You're already playing the easy mode. You have to click off the echo to see the normal mode and you still have the benefit of i100-i110 gears to soften that.

This is endgame, you need to be able to learn mechanics and find 7 other people that are capable of the same.

It's also old content, it's very easy to look online and find info on every mechanic in the encounter.

What you want is youtube. If you don't want the satisfaction of clearing difficult content, watch a video.
