I could have sworn this had been done one way or another and my argument is the same, from actual shown vids and images Kefka takes far too long to use any of his abilities, 3 second sfor that laser, probably longer for any other ability vageuly useful.
Kain could just teleport/slash and catch Kefkas head as it drops or even better drink Kefkas blood, gain his powers and then amuse himself by allowing Kefka some glory before stopping him in his tracks with ease.
Also youve not taken away time powers, repel shield etc so youve negated Kefkas normal speed anyway as well as his magic.
Because those who have extreme power are too slow to be able to use them and he himself has powers that bypass various defences. His own defences being fairly imrpessive. hes not an easy entity to hit, let alone kill and thats not because he is physically fast but his teleport and mist powers allow him to escape many things unharmed.
No I said he has negated kefkas magic because hes got the repel shield which reflects magic back on its caster. I have not played the "kain can control magic" card yet. Kain does indeed control magic but he does not need to do it, in this fight he is too quick for the magic to be worth doing and can cast time slowing and repel shield before Kefka can do much at all.
Thats irrelvent, if Kain could blow up the universe but it took him 3 years to cast the spell would that put him on a level far beyond all these characters who can only bust planets? no......
Theres more than just the amount of damage you can create, first show me him doing it within a second or so....then you may have an argument.
