I never had a problem with TJ Combo, maybe its cause of the characters I play(mostly newly released characters) who for the most part have good match ups(Riptor, Aganos and Kan-Ra). The character I always go well there is a lost is Spinal.
Right now he feels fine, and probably will be mid-tier after the nerfs. He in general feels balanced, his weaknesses are his risk moves and unlike other characters he doesn't have that much benefit from extremely useful shadow moves, and his strength is his combo ability. I like the fact that TJ Combo is unique by taking advantage of the combo system in place and his strength isn't one you usually see.
As for Ultra-Combo forums, yeah I really don't want to talk shit about another forum but sometimes I question the intelligence of that place. I read the dumbest arguments for the most miniscule topics.
