After recent discussions with veterans of the game I am convinced now the game features at least as many hidden mechanics as clearly explained ones.
half of the perks work differently from whats explained, movement is much more complicated than explained and weapon functionality is a complete black box for any player who doesnt read the not publicly available game files.
this is very bad for new players but even for veterans it causes many problems & unnecessarily degrades the quality of the game.
I recommend gaijin makes a post regarding all of that. Important: it doesnt have to be complete or 100% right, as long as it just sums up most things it will be a significant improvement compared to the current state.
