Believe me when I say this, that Seth is quite an easy boss to fight up against, even at the hardest lvls, in comparison to SF's past bosses...
Let me mention these...
WW. Bison - Instant Scissor kick lockdown's with no charge, and if this connected, he could auto-link to another scissor kick lockdown...bam, 4-hit combo, you've just lost 75% of your 100% life. His Headstomp had an auto-lock on your character, and his throw alone took off as much as mp strength Zangief SPD.
ST. Akuma (ST) - Dual Air fireballs, comboable hurricane kick, stupid ashura warp, 3-hit shoryuken no matter what lvl, CE/HF Ryu speed Hadouken's, super fast 3-hit Hadouken, throw range almost nearly as far as Zangief's, and twice the speed of Ryu/Ken.
Alpha 2 Akuma - Literally one of the most stupid Akuma's EVER, period. Dual Airballs for Alpha 2 were different then all other "Shin" Akuma's in that both of them traveled in different but perfect directions. Making it impossible to avoid one or the other, where as all other Shin Akuma versions, it traveled in almost relatively the same vicinity. His Dual Air fireball in here is the most broken version out of any Shin Akuma ever bar none.
He had instant recovery from his Ashura warps, so he could SGS instantly off of it, any sweep's that you whiffed ='s Super Fireball counter from him or worse yet a SGS that took off nearly 80% of your life, and traveled twice as fast along with the distance.
All three of these SF bosses were way more stupid in their game then Seth actually is in SF:IV. Seth is very beatable, and the biggest differences is that he doesn't do as insane damage as the ones above, and his although they have strong priority are no where near as stupid as the ones above. I mean, the amount of damage Seth does with his Ultra, is like equivelant to the amount of damage WW. Bison would do if he just landed one scissor kick to you.
As for Gill he isn't that difficult at all, simply because with Parry, and the fact that cpu's are very readable, you can literally parryxxpunish him to almost oblivion. Alpha 2 Shin Gouki is still by far imo the most retarded and overpowered boss within the SFII/Alpha/III series, and yes including IV.
On a side note, my old boss from Gamestop gave me a call to join in on the tournament, I didn't go to join, however I did show up for a little bit today and did a bit of casuals before the tournament actually started.
I played 24 casual games with 14 different players, and out of the 24 sets, I won 21 out of 24...on the CRAPPY 360 Controllers, rofl!!!
Funniest thing was, there was things that I completely whiffed on, or just completely mistimed due to the atrocious 360 d-pad. Oh well, it was fun to mess around, and to be honest, if I'd of been serious and really taken my time, I wouldn't of been surprised if I had won. The only serious peeps there that I would've worried about a bit would have been my cousins and a few friend peeps I knew...basically people I used to play with years ago...rofl. Go figure, oh well, I left before it started and wished everyone luck.
Hope anyone here who actually went to the tournament that you enjoyed it, even if you didn't win, that you at least experienced it and had fun.
Anyhow, I'm done with SF:IV for a while, need to work, and I have some projects due in soon for my job, so I have to focus on that. So no more Hadouken's and Shoryuken's for a while, but I'll make sure to check up on here in case some peeps have questions that I could possibly answer if I knew it.
Peace All.
