Team Balance needed in Arena

It might just be my bad luck or paranoia, but it seems to me that every second game or every game I play ends up being a 3v4 or so on very rare occasions do I get a solid 4v4 match which i enjoy. If it’s 3v4 there should be soething to balance it out or give a handicap, since it’s not fair to anyone on the shorthanded team to be dragged down because someone decided to back out at the last second. Any ideas ?
