I'm not too fan of this new feature of 3v3 arena but there's something really boring about it. It's a pain in the butt to change teams from one line to another. Couldn't you add a feature that allows us tu move an entire team from one place to another ?

 I mean taking all four heroes of team 1 to team 3 location (for example)  in one click instead of deselecting heroes one by one then reassigning them one by one again.
