There is a few usability problems that i have found while playing.

First of all: Info messages

Info messages from the system (people leaving and things like that) are displayed over game chat, so you canīt read chat and it would be a problem noticed more between matches. They should be moved to a zone where info won't be hidden.

Group chat: there is no group chat out of matches, so you can't comunicate with groupmates. I know there is a Ubi chat, but it isn't a excuse for not having a proper chat.

For keyboards user:

There are a lot of problems with aiming system. Since last patch i have found a lot of times i'm fighting more than one people, attack, change target but second attack go for the first target (I donīt know if gamepads have the same problem) That's a Huge problem because we canīt choose which target we want in keyboard. switch key just get the nearest enemy so you can stuck in the same two opponets even a third opponet it's damaging you! Can ubi change switch target key for using it along movement keys to choose direction of target switch, similar to right stick in gamepads?
