I don't understand why Stormraider's Surge can't just exist as it is for next season

Grasp of the undying is almost EXACTLY the same keystone as it currently is. Press The Attack is just a renamed Fervor.... etc etc....

Stormraider's Surge is currently the most balanced keystone in the game. Of course it needs some improvement, like turning it from 30% max HP to 30% current HP etc... but all in all there is absolutely no reason why it can't just exist in its current state for next season. I'd rather have a viable version of a potentially difficult to proc keystone, versus a really weak keystone that is easy as hell for anyone to proc.
