I would like for all tank classes to have a bigger influence on the battle.
If you look at the feast leaderboard it's pretty clear which roles that weighs the most heavy.
A good tank might have a 53% win rate while a good healer got 70%.

Maybe lowering the CC resistance time by just a few seconds could make tanks more useful and also allows DPS to capitalize more on oppertunities. Basically would draw down healer win rate a bit and increase the rest.
