"another" indicator; have we seen evidence at all of it being dumbed down for consoles? Besides, in Warband sieges everyone spawned just waiting for the tower to reach the wall or they all raced for the ladders, archers included- and why would you need to use more than the default number of groups for a siege, let alone lumping archers with melee? In most situations, you want your archers stood outside shooting while the infantry attack, not running along with them, though it could be useful I suppose if you wanted to make that group all stand still on top of a tower once inside the castle; the infantry could stop enemy melee from reaching your archers. The point is, the fact that they didn't seem to be using more than the default groups doesn't suggest that the ability to make extra groups is suddenly gone.
