I've done Enrage method a few times in DF with just the 2 healers and no bard.... one was even with 2 scholars. It really depends on people's gear and how they play their class. I see far too many monks and dragoons attacking ADS from the front and not maximizing their damage. Sure you have to be stacked, but you do have the freedom to move around a bit assuming everyone is on top of ADS.

I'm actually curious if anyone has tried destroying the Rot node. While it does apply a haste buff to ADS, players are now decked out in i90 gear, High Voltage has been nerfed significantly, and there's the echo buff to boot.
