From talking with them, no. Their play testers struggle to get past 90 stacks of voidform with StM. Shadow is not exactly skill gated either, atm it's put up and maintain dots, then follow the priority list.
I wonder when they'll start talking about the real issues like the massive time sink that AP grinding is and how punishing it is if you miss a day or two at the competitive level.

Also, did some tests with MH capped at 50 and 75 just to see what it would look like. StM was still ahead by at least 20k.
