To use a recent example, last night a small comedy of errors dring the T12 add phase had our WHM on the floor around the 11th stack of Flames.
Turns out that it's fairly impossible to counter this mechanic as a solo SCH once your stacks get that high. If pushing only 3 Bennus, I could see it with appropriate use of CDs, but my group's total DPS isn't yet high enough for this.
Now, if I had died instead of the WHM, it might have been possible to complete the phase.
