Normal Raids need dps check and enrage time

[Chasingstars]

It's not really about making normal content harder, just making it so that you can't clear it by just outlasting the boss and people will have to actually contribute to the fight.

What you want is type of enrage where the boss will inevitability reach the stage where the players auto-lose, not "kill the adds before the boss reaches 100" enrage. Which is making the content harder as there is less room for screw ups. Savage and extreme are right over there if you crave that kind of content.
