Out of curiosity, are these people tending to use the Angel Wing , or do they save meter for Resurection and just do his big juggles?
…or do they use that big Meteor shower combo?
Just curious if they gravitate towards one in particular, might be able to give better advice if I knew. If they play it smart and use them based on the situation, I dunno what to tell you, Gill is a monster.
Oh one thing I can think of , this isnt anything game breaking but punish the block dive with an AA or juggle of your choice, since he bounces back helplessly if its blocked. I think you can punish his dashing clothesline if you block it, I have to confirm that though. And of course punish missed fireballs any stupid use of the meteor shower.
Unless theres somthing Im aware of he doesnt have a major weakness. Ive never fought a human Gill, aside from my brother, so Im just kinda going off what I know about Gill from the computer. Sorry I couldnt be more help, but I really dont think there is much you can do except take your opportunities as they arise and hope for him to do somthing stupid. Its probably best to just poke and go since he has such fast high priority and high damage normals.
As far as characters, Id go with Chun, Yun (if you can do the Gill juggle, if there even is one), Hugo (use the 4 taunts and Gigas as your super, Go for Broke Hugo:tup: ), and Urien if you can do the big stuff.
