i think this tpoic should be split between nsg challenge and a full sphere gird

What I want to know is this, do you have all your characters at 255 maxed stats completely? Not only that, but the Aeons also need to be at 255 maxed all stats as well, in order to achieve 99,999 damage per hit.

However, I cannot say much, since I never played the version which had the "Dark Aeons" as you say, or the International version, my tier listing is derived from the one within the US only. Even regardless, Yuna w/ Yojimbo for Zanamoto would still be undisputed in any version.

well i agree wid tha tier except for ur decision on auron im not startin nyting here but it all depends on ur lvl for ur characters
my top 3 for my party are:-

tidus - good for attackin in speed nd strength
yuna - her aeons r powerful nd her healin is essential for battle
auron - very powerful at attackin armoured fiends nd bosses nd good for armour break nd ting lyk tha

i also used wakka for attackin flying fiends nd lulu for elemental fiends nd rikku for stealin useful items i rarely used kimahri as most ov his attacks u av 2 collect from different fiends which take up 2 much time

I totally agree with the list, except maybe Rikku. She could do with going one place higher. Other than that its correct, i dunno how you manage 12+ hits with Fury though..most ive had is 10.
