This game wasn't made to be realistic, that's why its's so fun.
A dev even. said that this game was supposed to be what WW1 COULD'VE looked like. Also I haven't seen a single hacker (I play console, maybe it's a pc thing?). The only problem is I think the UI is a little complex, but is still useable.
There was one guy that said this game had no advanced movement, of course it doesn't. If you want advanced movement play Titanfall 2.
