This is a very small tweak but I think it would help with QoL and also guide players into more matches and improve queue times. 

Right now it takes 4 actions to go from the end of the match to search a new match, most e-sport games require just 1 action. 

Keep it quick, keep it simple. 1 click and the game searches for a new match with the same conditions/battlegroup/maps etc as before.
