The first is actually an issue that I find to be pretty annoying. You can't read a player's name unless you're very precise and land your cursor on them. If they're moving, no matter what distance, it makes it extremely difficult to read their name. I'm sure this is, to an extent, intended for gameplay, so it makes it more difficult to identify any traitors on-the-fly, but suppose if another player is within a certain range, their name will hover above their head?
I've noticed for me at least that it's harder to ID players now happened a few updates ago. I figured it was just something done either to balance the game, or something wrong with my PC clientside. It's kinda annoying.
