I dont think the problem is the meta.. But the fact that Yoshida and his testers say they don't include healer DPS, and then make the checks wildly high as if you have 0 downtime for DPS at a reasonably geared level. This is assuming the Main tank at the time is always in Tank Stance.

It's a little ludicrous in A3, just because there's so much moving, but otherwise it's okay.
