Force Players To Engage With Boss Mechanics

It's really bad that end game pinnacle bosses are basically getting 1 tapped on the hardest difficulty before even doing an attack.

I've seen arbiter of ash kills repeatedly done with 500 rarity and it takes about 5-8 seconds. He doesn't even do anything meaningful.

This not only trivializes the game, it also means players will just repeatedly run the boss over and over, pumping the market full of their uniques lowering the value. It actually makes doing the boss run NON-PROFITABLE in 95% of cases.

Potential solution:

Anti-DPS aura - if a player is doing DPS that will melt a boss the boss before it can do anything it can cast an aura to slow damage dealt by 90% for 10-15 seconds.

Limit player power in the very top end (0.001%). It's already way too high.
