I can't promise to get any games in (I really want to!), but some combos I'd be wary of:
Tarn + R7 + IA + Etheric Rudder.
Tarn + R7 + IA is already fairly tanky, so this could put him over the top. However! At PS3, he is easy to fly around.
Similarly: Luke + R8 would be basically guaranteeing an evade result every time. This might not be OP, but would be worth looking at.
