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

After the patch I'll need to find a static group or manage to convince a bunch of random people in DF to click off their buffs.

You'd need to find a static group anyway. I highly doubt a random party thrown together in the DF can beat t4 or t5, even with the Echo. Even though the EX primals are in the DF now, you don't see DF parties actually beating them. Coil will be no different. DF it for practice, but if you want to seriously have a chance you will need an organized group. The Echo will NOT remove the unforgiving mechanics of the fights (it will just make some recovery easier if someone DOES mess up).
