I've been hearing lots of posts about the usage of SW in pve spell rotation, and to be honest I'm still unsure. Its not the self damage thats the concern. Its whether an instant dmg spell(10% bonus chance crit from 4 set t7.5) is better than Mind Flay(has 3 chances to crit).
Mind flay definately feels smoother since i'm using all of my GCD channeling, but SW has a larger crit chance which would then proc spirit tap/glyph of shad.
Since this is hypothetical, lets say we're fighting a stationary boss that doesn't require much kiting,(since SW would be at its prime)
Any thoughts/data/ on the matter? or stories about the lingering pain from the WotF nerf
