Some matches are too lopsided for the first team fight win, that it requires a premade to even be able to come back from. Wintergrasp for example is extremely broken in may ways, for one, everyone gets Rank 1 at 5 minutes, but it never gives everyone Rank 2 by a certain point in the match too. They should probably auto award Rank 2 at 10 minutes and once any on the team gets Rank 2, anyone spawning into the match, should auto jump to Rank 2 instead of Rank 1. This is just one example, there are more.
What add on is that highlights healers?

It really sucks that epics even need premade groups. People are just so quick to ditch a battle when it goes "wrong" at the start.
