I hate the idea of Echo Buff. It should be part of some easy server not whole game.

They need it, a lot of people who don't have the skill to complete some of the harder instances are leaving the game, a game that caters to casuals can't afford their core audience to leave because they can't beat some content. I'm not a huge fan of it, but you can toggle it, so you aren't forced to use it.
