Would still kill the character IMO. Just think about this for a second
A clash will give you, with no meter use from the opponent, a max of 33% life back.
A raw grundy pain chain is 31%, and any combo into pain chain is >33% . That means when someone clashes grundy they just wasted 4 bars to get back what he does in a trait grab. The best thing about clashing grundy is it puts him full screen. I have found the best way for grundy to build meter is in fact his reset, doing a 3 bars of resets takes away 100%+ and gives him a bar of meter back. A dead guy in two bars, while getting a bar back and you want to take his reset away?!?!
You do realize that the "reset" will still probably exist... just not in the capacity that you are wanting it to be
I've lost more games than I can count because most of my damage comes from the clash, and because by that time.... I usually only have a bar left.... so they gain all the health because Grundy needs his meter.
I'd much rather be able to just drop a combo and go into the pain chain knowing they'll die every time. That alone would create more fear and more mistakes. Now that they can clash the pain chain..... there is no fear of guessing wrong in the "vortex"... because they'll be able to clash it no matter what. It used to be you could drop a combo (usually at the MB SH part) and time out the grab so that it didn't combo and gave you a free 31% for the win.
So yeah..... i would def. want the reset gone if I could have my unclashable trait back. He still does 50%+ damage on almost every touch. IF they took away just a few frames of advantage off b1.... you'd still be able to toss out f1,3 and mixup from there.
Grundy was much better when you couldn't clash his trait.
