1) Movement spam (ADAD spam, crouch spam, jump spam): I thought these were WW2 soldiers, not futuristic super soldiers dodging bullets like Neo in the Matrix. Also, the fact certain guns have zero accuracy penalty (mainly Assualt DMRs are the main culprit) when doin these crazy manoeuvres, doesn't help.
2) Wall Banging: The art of showing none or a few pixels of your character through cover. Basically impossible to hit these people, and they have zero counter. Yes, cover can block the body, but your head should then be a juicy target. So many times, it isn't, due to this problem.
3) Invisible players: Either they only pop into existence after they've killed you, or even on the killcam, they are invisible. This is due to latency, and is squarely the problem causes by bad servers. I didn't realise we were still using dial up internet lol.
Dice, IMO, should prioritize these problems, becuase they are universal problems that ruin this game. Everyone would benefit from these problems being fixed. Like if you agree.
