The Chat for example. It's a joke. The non-scalable input field? It's pathetic craftsmanship. I mean, I could name about a dozend of other terrible designs and usabilities. Or is this the passive aggressive way of telling the user that you don't want users to use the chat as a messanger between friends,
And the scrolling? If your scrollspeed is ~5 lines, you skip 2-3 lines that aren't reachable unless you use the arrow keys.
Embarassing work.
