Finally played the patch last night. While downloading it, I was testing out the changed stuff before it was changed.
Reflect shows 15f startup where it was 16f before... the 23 in the patch notes is from the recovery and an oops on NRS' part. It really doesn't feel any faster on startup to me as I literally tested it before patch to after patch very quickly.
I also noticed that the frame data on b1 has changed to 10f from 9f. I didn't notice a difference when using it so perhaps this is just a fix in the menu?
Here is my stream archive where I tested 212~EX Glaive against every character:
You will notice I did not have Jason and Kung Lao crouch block, so they are a bust... but it's good from there. I really only tested this against armor through the return glaive against one variation per character... and I only tested a backdash punish against Takeda which worked against his armor and backdash equally. His armor is 23f so this wouldn't work against other characters.
It is obvious that backdashing is what you want to do against this, but it opens up yomi for the Kitana player to make a read and punish.
No timestamps right now, but if someone wants to do it...
