yeah i know that, but if rockets get destroyed by active protection it shows cross mark on the hud, and i clearly saw that tank had no protection active when i was shooting him. Also its not explaining why I cant shoot helis (in the first few days/week after release I've destroyed tons of them with RPG). Yes, I know that maybe they did it so heli players won't struggle that much, but helis are still weak and easily can get shot, so its pointless.
Im 100% sure they did something to rpg so its not that strong against air vehicles which is not fair imo (they shoud've decreased damage instead of making rockets explode mid air). Its still good against ground vehicles though.
