Well the hp difference imo is not a big difference. I would have like to see the Defenders have about 8 or 10 per level instead of the 6 which is only 1 more per level than the others. Not enough difference imo. I know they get better armor and con is more important to them and they also get more healing surges but the should have more hp imo.
Barbarian beats out the other strikers by getting 2 more healing Surges regardless of Con and an extra hit point per level and 3 more at level 1.
He has a dependancy on Str and Con and if he wants a decent AC he needs Dex. Dont see much of the need for Charisma in this current build.
A barbarian has a chance to use a maximum of 2d6 or 1d12 damage by using a two handed weapon. His main damage ability lets him have 2d6+1d6+str mod. The closest is the Ranger at 1d10x2
A barbarian has a pretty hard hitting Encounter power or one that lets his attack alot of enemies where his damage goes up with the number of targets. Compared to the rangers ability this is (2d6+mod+1/adjacent enemy)/target vs (1d10+mod)/target. The other power released is a 3[2d6]+str mod+con mod but your attackers get a +4 bonus to attacks vs you till the start of your next turn. Compared with the Ranger you can get 2[1d10+str mod] + Wis mod or you can do 2[1d10]+strmod and can shift before or after the attack.
As a daily we get a Rage benefit and 3[2d6]+str mod. The rage benefit is either an increase in Speed and shifting or a bonus to damage if you or your target is bloodied equal to your con mod. The speed increase and shifting increase tries to make up for the lack of mobility options compared to the Ranger or warloc and the damage one is too help with the lack of additional damage per round from the quarry, sneak attack, or curse. the Ranger daily power that is closest does
2[1d10]+str + 1d10 and leave the target weakened if the second attack hits. You get to shift 1 sq during the attack. the other abilities have 2[1d10]+mod x2 or 2[1d10]+mod per target(max of two) or 2[1d10]+str +ongoing 5 + slowed
Rogue doesn’t compare as much as the weapon choice is very low and keeps damage to about 1d6 but they have alot of benefits.
warloc has a static non weapon damage set up that is about 3d10 at the max and 1d6 at the lowest.
Ranger is the best comparison by abilities alone.
Barbarian lacks mobility that the Ranger and Feyloc have easy access too. Barbarian gets Temp hit points like a helloc has. The Helloc starts to surpass the number of temporary hit points unless you can keep the Con maxed out and even then at about 6th level you get surpassed. The benefit is that your Barbarian doesn’t have to designate a target before hand and can swoop in and steal a kill to get the benefits.
The Rogue gets a 2d6 a round if it can get Combat advantage. a ranger can pick a target to apply a 1d6 damage as a minor action and as long as he does damage to the target of his quarry. The Warloc curses people and can have a huge pool of cursed enemies. If it does damage to a cursed target he can add 1d6.
Ranger has a lot of shifting abilities built into powers. Warloc has some powers that allow it to move or to move its targets. Rogue does alot to slow people down or take away thier actions while allowing them to maintain combat advantage.
Barbarian lacks a lot shifting powers. It can Charge an enemy when it reduces a person to 0hit points. It then gets to use a power that does more damage. It also if raging gets to ignore OA’s. Where the other classe are good at movement in general, the barbarian is good at closing with enemies.
The other classes get a if it hits then we get to add damage. 1 is confined to combat advantage, the other two have had to designate a target first, and the Barbarian has to crit on an attack roll. if the barbarian is using a 2d6 weapon he would then get to make another attack for 2d6+str mod. So first he has to crit then he has succeed at another attack roll to get his damage. Not over powered, but possibly a little underpowered.
The Barbarian gains extra damage if it attacks a Bloodied target or the Barbarian is bloodied if it uses the daily power that grants this type of rage.
A Barbarian’s extra damage is very conditional. It gains temp hitpoints but since they don’t stack there isn’t an overpoweredness about it. It stays down to about 5 at heroic. The thing that makes these better than Locs is that barbarians potentially can refresh these as many times as there are opponents. A helloc would do fine like this but he most move to get close to curse so it takes a bit more effort on his part.
A Barbarian’s daily powers all provide a rage benefit. if you use a daily it applies the new rage benefit over your other rage benefit. Since they are daily you must put up an extended rest to get them back. They gave you a power that if you wanted to use a daily for the damage potential but wanted to keep you current rage benefit you get to expend the power and do damage based on its level through the power Rage Strike.
Rage Strike is pretty weak for 1st level till about lvl 5 when you gain a second daily and another rage option. If you like your level 5 rage benefit you can expend your lvl1 and get 3[W]+ str mod which is just the damage of a 1st level daily.
Barbarian seems to suffer from the fact that you would want to use yoru daily early on in an encounter to better benefit from your rage benefit. With Rage strike you have an option to use a daily like other characters can but you don’t have to worry about overwriting a benefit.
A barbarian will also want to use its daily almost every encounter. Then it will want to immediately take an extended rest. Maybe they should retry this or you could potentially be back at the Wizard is out of spells lets rest cycle they want to break.
It has more hitpoints and 1 better Armor than the other strikers. Unfortunately Ranger and Rogue both have a nice reliance on Dex. Warlocs like Int. Now with Ranger and Rogue these can potentially be the number 1 stat(rogue especially). Warloc’s tend to take int as a secondary stat so they will have a decent ac. A barbarian needs a great str score and a good Con score. The class tells us we need charisma but Dex appears to be more useful so far.
Barbarian also has the least amount of trained skills out of the four strikers. 1 less than Warloc, coming in with 3 total.
Barbarian appears to be Balanced but yet more on the underpowered side. With a good stat set up and decent 2 handed weapon the barbarian can do some massive hits. Rogue and it will suffer from the 1 attack roll for the sum total of damage vs a Ranger usually have 2 attack rolls for the potential of at least 1 hitting.
So in all my ramblings without actually playtesting it I am going with Barbarian does very little for the Defending role and lacks the unconditional mobility of a Striker along with easy access to additonal damage. Not over powered but a little underpowered.
