Demon wall little too hard?

[Aenarion]

Demon wall is nothing more than a dps check, the mechanic itself is very clear

Yup, not that it'll stop to terrible DPs from blaming everyone else but themselves. Had a DF group yesterday that took about 12 min just to get through to the first boss, and when we kept wiping to Demon Wall because they still couldn't kill the adds after TWO repulse cycles(while keep getting hit by the floor), the SMN turns around and say that the problem is that they aren't getting enough heals.

I'm usually very patient, but at that point I just gave up and left.
