This is cool because you can always escape by back dashing (after the air throw whiff or after b+1,2,2 inbetween the string and sunstone) or armor (if it's a really fast armor after air throw whiff or before the sunstone is thrown). The Kotal Kahn player also has to be perfect in order to avoid being low profiled since there are points where KK is only at +4 on block. Ronin's is cool too for the same reason. It's not fair that REO wants to ruin the frames of a string which will potentially destroy Takeda's ground game potential just because he doesn't feel like backdashing or using armor. If he takes the hit, then the block infinite is over because if he literally lets go of block on the last hit... the player most likely won't be prepared to hit confirm into a substantial juggle.
With as much ruthless stuff that Tempest Kung Lao does and that's just an accepted part of his game, to go after other characters is biased and wrong.
