I think they should probably not do fixed damage in order to keep the players guessing for a little longer.
The players, technically, are not supposed to guess at who is a minion. According to Mike Mearls they should be described by the dm in a way that the players know they are minions (ragged leather armor, rusted weapons, etc.) personally i would cringe if the PCs used a daily power to take out a minion 
On the flip side of this topic, one of the things I hate most about this edition is the spoon feeding of players that is inherent to the game. The scales have been severely over adjusted to tip heavily in favor of the PCs. While I am all for a game where the heroes almost always win, if you remove the element of chance it really ceases to be a game.
I too would inwardly cringe if a daily power was wasted on a minion, but there are enough other tells that players can look for to keep them from making that kind of tactical mistake without me spelling it out for them. And if they do, after all the other clues, still make that mistake they have no one to blame but themselves.
