I am not comparing him to an imp with a toothpick or whatever! He is strong but not strong enough. If you're not gonna take a word I've said in, then I'm done. I keep pointing it out but you completely miss it! Seifer's abillities and attacks could not damage Seymour! They're to weak!! That's it in a nut shell. He can't hardly hurt Seymour and the only attacks that can trully damage him are his Limits!
About Cura, it is powerful and could easilly render everythin Seifer's done to him to nothing. You didn't even mention Seifer's Cura. I said that Seymour could cast magic and kill him. He could Cura himslef but Seymour could just attack again and again.
You know, I honestly don't think your brain can take all this in. You seem to understand the corner of what I'm saying but not the whole concept.
