I think that explosive ammo for M107 sniper rifle should be forbidden on KOTH HC Infantry or even normal KOTH game mode.
You can kill a lot of people without even properly aiming, just splash damage.
I saw about 7 people dying while dropping from heli just from a few shots in few seconds, then I got killed by him. M107 littlebird sniping is even bigger issue, because we can't buy stingers on at HC Inf game mode.
The thing that make me angry with that was when I was hiding behind the wall and just got killed by this ammo, which were shooted about 2m near rock.
