A vote

I'm making a small referendum on what the community would like to have improved most in the game engine, in order to give the staff a bit of feedback on what we see as priorities in this game. this is directed toward all players, casual or competitive. Please copy the following issues, with a list of them, in order from most to least importance to you, and give a brief reason as to why.
*please note, this isn't improvements that can be made to the community, obviously. This is strictly things in the game engine.

Mouse movement - I really, really don't like how choppy and erratic the mouse movement in this game can be. It's quite disgusting, and can be a turn off to new players.

Registry - even when I aim my mouse right, which takes a considerable more amount of effort than other games, and make a shot and still don't damage/kill the opponent because of poor registry, it can get very frustrating.

Cheat engine - hacking has always been a large problem. And even though I myself don't pub often, occasionally I'll see a blatant hacker and get angry.

Random disconnections - Rarely you have a scrim, match, or pug without a disconnection on part of the game engine. It can be irritating and sometimes costly to your team.
