Feature request: Make joining teams easier in team battles

[Jeffforever]

In team battles, people often don't find a way to join a team as they haven't done it before. For example in Streamers Arena,
following was written in chat by several people:
"How I can join to a team", "How can I join one team", "How do i join", "How to join teams", "How do you join?", " How I can join team", "How do i join".

I would therefore request to add a button to join team on the overview page instead of only sending them to the team page. There are simply too many clicks / barriers for people to find how to do this. In addition to that, one shoud also consider "Leave team" if we would add such "Join team" button in that space:
