Its weird; out of all the strategies I see people and the AI use, THIS is the one that irritates me. There were times where I was literally piledrivered out of my super. I figured if I go against them both a bunch of times, I would find a strategy, but so far, no good. Any tips?
Either jump or backdash out of command grabs. There is several threads in NSD about dealing with them.
If they are standing next to you waiting to do a SPD on wake up just back dash away.
