1. Remove speed run style content. Reward players for 'smelling the roses'
2. Remove interrupts and CC from tanks. Give more interrupts to DPS. Punish DPS only for missed interrupts. In exchange, give tanks more raid CD's and remove some from DPS. Highlight DPS errors more on the UI
3. Increase tank threat significantly
4. Double the current HP of tanks, more active mitigation,, make outside healing received from others less potent
5. Make more interesting mechanics for tanks where there is more interaction with active mitigation
Result:
1. Tanking is now about managing resources and active mitigation, not about making DPS lives easier
2. Getting rid of the 'gogo' mentality
3. Tanks have more responsibility of their own fate
