I used 6P+K almost all the time in DOA4 as a whiff punishment move and first move to go into a stun mix up and it worked wonders at times. Now it´s almost useless out of stuns...
And you coulnd´t throw break in DOA4 too and 46K was still far from being overpowered even if it gave +5 on block.
And 4P... really? I don´t think most Ein players will use that move on high level. Just not good enough.
There is nothing stopping you from using a different whiff punisher. Ein isn't exactly lacking there. All 6P+K gave you was a crumple stun, and the entire point of playing Ein is to ignore the stun game as much as possible. Use Azuma or something else to push people closer to the environment. That's where his damage comes in the strongest.
46K and Hayate's variant were used exclusively to get-in and dominate DOA 4 matches at high level. I'm not sure how much you were exposed to it, but both variants were used by Offbeat and PL to get inside when they were not in turtle mode. If it wasn't ridiculously effective, people would not be mourning the loss. It's still a good move, especially since Ein can take a third lifebar from his high jab string on CH now.
And at the rate Ein players are complaining, I don't think there will BE any Ein's at high level to use 4P. If you doubt its effectiveness, ask Perfect Legend. Do not forget this is a string that goes into launch.
