Apart from the main problems such as lag conpensation which seem to get worse with every update I download there are also some problems that need addressing.

Final kill in any game minus TDM does not count towards challeneges. Demolition etc.

Grenade challeneges such as master chef only count on TDM.

Stealth Bomber glitch.

Under maps glitch.

Grenades blowing beside people and only getting hitmarkers.

Enemy shoots you with a rocket point blank and does only damages himself.

These might be minor problems but Its annoying for doing challeneges that Im stuck to TDM.

And the list goes on.
