Did some testing yesterday and noticed that in Single player/local play against bots, TTK was drastically better than online play, Requiring only 3/4 shoots on average to kill and was also very reliable an consistent. Online Co-op/PVP on the other hand was the complete opposite, Requiring 5/6 shots sometimes more to kill. Seeing this makes me conclude that its a net code related problem and not Hit-reg like alot of people are saying. Noticing also that having more players in the server compounds this problem, Leads me to believe it further. Whether its a de-sync/sync issue or tick-rate related problem, Its for sure a net-code problem and not bad hit-reg. Im sure you are aware of this and are doing your best to resolve, Keep up the good work!
