The throw priorities are indeed fucking stupid, especially seeing how throwing has been changed for the worse from SF2 > SF4, tech'ing a throw in SF2 is easier (somewhat, you could argue that the speed of the game makes it harder) but it also leaves you with a bit of damage, instead of nothing at all like in SF4.

Opponents being able to block your ultra while it seems that they are in an active frame state is probably due to lag.
And yes people like Ryu have a 1001 ways to effectively land an ultra, while someone like cammy only has 1, which is as a counter on active frames.... so fucking rediculous.
Sagat can even first give you his super, then follow up with his ultra, and land BOTH 100%, so stupid.

I still enjoy hdremix more then sf4.
