I have played on the last patch a bit, IRNV is a bit overnerfed/useless on most light maps if you ask me, but they are adressing this. Mortar is useless now, I think they should've changed it to 4 rounds per spawn(not able to regain with ammo pack), not nerf the damage/radius so much and give it infinite ammo.
I love that they will change rockets effectiveness on infantry, it's retarded on some servers where people keep abusing this.
