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

For people who have already cleared the content: it doesn't affect them.

For people who haven't cleared the content: its a completely optional buff that can 'help' them clear it. If you don't want a difficulty decrease you don't have to use it. Form a non-echo coil party.

What exactly is the problem here?
