That's pretty much why I think the IG players should be "Officers" in charge of their platoon. In short, they will be the minion masters, and will be able to specialise their squads to be DPS, or tank or debuffers.
And if they don't, well, they'd be stupid, because having a ridiculously numerous army is the whole point of the IG. Make each of the factions special in their own way, and leverage it to make it pleasant to the different kinds of players.
Hmm.. and now I just have the desire to play a Minion-master game of the like of Overlord, but as either a Tyrannid Lictor as the main character, or maybe an Orc Boss. You could even have a IG commander. Multiplayer would be a blast.
Although the S.M. would be a bitch to fight against
