You're "trying" to know what you're talking about and failing =/ Grapple characters in Tekken can be played much more offensively and don't need to rely on their throws as much as someone like Bass or Bayman. Kings and Armor Kings "Giant Swing" does at least 30-40% damage without wall damage, that's stronger than all of Goh's throws in your provided example. I'm not understanding where you got 10% health from. You're examples are biased stating grapple characters in other games are better. King, and armor king also have throws for maximizing damage, resets, and positioning.
You mean his techable giant swing? The one everyone decent either breaks or techs when thrown. he's got a few good throws but the majority of his stuff is useless against anyone who knows what they're doing. he's got like a hundred dam throws I expect something better
