Tiger Raid is still such a sick animation. I liked that many of the ex moves in SFV look like old supers animation-wise, so I was a bit sad when Capcom never brought this move back in some capacity, despite it being in Omega. (Same for Shippu Jinraikyaku and KKZ tbh).
i almost exclusively use omega, it's WAY more fun to use for most of the cast imo. my friends don't use it though, so.. you can imagine the matches we play when i pull out some omega shenanigans they don't know about 😭
DP FADC on block was removed across the board in SF4 Omega. The only DPs you can FADC on block are the ones which aren't invincible (e.g. sakura). Most characters kept EX DP FADC but that's 3 bars to spend.
