Everything worth mentioning has already been pretty much pointed out.
The Tiger Raid is pretty devastating, his Super having some actual viability, crouching light punch being easier to link, and the standing medium punch being cancelable is pretty neat, but all in all, I’d say Omega Sagat is very incomplete. And since Edition Select is the name of the game, you might as well just pick Vanilla Sagat, since that is the most complete version of the King.
Capcom obviously didn’t know what the they were doing when they altered this character in Omega. The job they did is very half assed, just like USF4 in general is half assed. Very untested, very incomplete.
And as Mnszyk mentioned, his forward light kick into jab link seems to have been removed, but instead, makes a heavy impact sound in which you cannot do anything afterwards. Its ridiculous… like Capcom wanted to do “something” with it, but never got around to it.
All versions of Tiger Claw are very punishable. The Light version seems to be most applicable since it hits low. Some risky mixup opportunity off this for sure. The medium version, and heavy versions are only good when hit confirmed, maybe for visual/swag/styling purposes. Jumping roundhouse, standing heavy kick canceled into heavy Tiger Claw does a pretty reasonable amount of damage, but less damage as opposed to cancelling the heavy kick into heavy Tiger Uppercut.
One thing worth mentioning… his Close standing medium punch comes out crazy fast. This allows for combos such as:
Within close range - Cr.mp -) close St.Mp or Cr.lk -) St.Mp . New BnB’s that when ended with Tiger Raid, does a shit ton of damage.
There is a new handful of combo possibilities Omega Sagat has. Once again, neat… but the tools aren’t nearly as good as what vanilla Sagat possesses.
My thoughts: Vanilla Sagat is still the King, but Omega Sagat has a gimmicky fun factor. Wish we could have vanilla Sagat back fused with things from Omega Sagat in the regular game, such as the special cancelable standing medium punch, the faster startup close medium punch, the improved crouching light punch, and definitely the new and improved Tiger Genocide (super).
I’m over 1.04 already. Looking forward to a better Sagat in SF5.
