Ridiculous. A gameplay patch should have come out 1 year after release, not one month. This patch should have been a glitch fixing or non gameplay related fix only.
At no point was sent broken because of his health. In fact, I don't even think Sent was that broken, he was just a really good character. His damage output was the key to him winning, he only domniated early game so much because people didn't know how the game worked as a whole, and since he was easy mode to do massive damage it was only natural he was going to dominate. Being the massive target that he is, he is going to die so incredibly fast now.
A list of things that should have been looked with sent without changing his health:
Removing OTG df Rocket punch to a non OTG (would decrease his damage potential significantly)
Hyper armour on S (why not have super instead)
Super armour on c.B (an easy mode mash reversal when someone misses a link in a ground combo)
70 frames on invincibility on harddrive (can get out of all air resets and all air pressure for free with one meter and leads to combo in corner, can counter in for free with 2 meters not on point)
X-factor damage (for everyone though, not just sentinel)
Why does capcom think nerfing health = bad character? It's the overall tool set of a character and how each tool matches up against the tools of other characters.
I love this game, and am probably one of the few people that didn't have massive issues with it, although I do think Xf damage output is too high, and generic throws are too strong. I agree with what Toxy said, playing a set team won't do any good if they are going to patch it every second monday. I am the exact sort of player who will benefit from this as well, since I play 80% of the cast to an average level instead of one team to a high level, but working hard to find all the advantages is something that should not be punished.
