No, just no. Bad idea. Let's not screw up balance. Squads suffer wipes all the time in this game, is just that the elite squads are more expensive. Chosing to play with an elite squads it's a risk that you know and accept from verry beginning. The risk increases exponentialy for every extra elite squad you build so you definetly should have a diverse army and not rely mainly on elite infantry. That high reward - high risk shit, ya know? Shocks are not unbeatable and now falls and obers neither.
Squad wiping is in the "shit happens" category and we cannot change that.
^siuking, the stukka is incredibly good at wiping. Your argument that australian magic is bad because he can't dodge a stukka barrage is ridiculous because anyone half decent is going to either predict your retreat or watch how you react and try to account for it in the next barrage.
One predicted side step, one predictable retreat and you've lost the squad.
I'm not claiming its OP, its an expensive unit on what was a lacking army (I ain't had a chance to play the new patch yet) but saying it and other axis units don't have wipe potential is uninformed, inexperienced nonsense.
