In big open maps it's not too much of a problem unless its airstrike spam fest .In field its way too OP ,I saw Nod wiped out(artys ,flamers and enginers)in the bottleneck base entrance .
Nod base has a tight bottle neck entrance they already have to deal with that and the Harvey that keep pushing them in field ,with airstrikes on airstrikes by GDI its OP and give no chance to Nod to get out of base .
I heard much complains about airstrikes from ppl that use to play renegade .
I think airstrikes is usefull but it need to be limited somehow not a spawn fest same on ion/nuke, the engys has enough to deal with it to disarmed with a need to deal with 5 consecutive AStrikes .
That's my opinion and so far I love the game and play everyday ,but this thing is my BIG Con of RenX and I will be and will speak against it, if its stay like it is .
