So far the open beta was enjoyable for me, but I found several things and a bug that I think are either lacking or have some potential.
1.) The running animation of the character is kinda too sensitive in certain situations - the character moves too much or just does a 180 if you want to turn only a little bit.
2.) Riding vehicles is pretty hard and they don't listen to you when you want to go do some nimble movement (the controls are either too sensitive or don't listen at all).
3.) You can control the recoil of fast guns only for about half of the time and then it just starts firing everywhere.
4.) On PC while playing with friends we had a big trouble with FPS drops whenever we wanted to synchronize our targets that are bound to the Q key - FPS kept droping every time we tried it and the game became unplayable for the next 3 minutes if we stayed near the targeted NPC's, or it would be okay if we ran away from them (with some hardship).
5.) I also think that the options for character customization are too limited and it would be a good thing to have more options.

These are the things I found lacking so far in Beta, but don't minunderstand, I enjoy it, it just feels that some things are lacking and could be made better to make the play experience way more enjoyable.

If you have other thought please leave them here, I'd like to know other peoples opinion
