Was about to post a question on possible kila choices, and ran into this thread. So instead of starting a new thread, I'll just post here.
I personally decided on a the 6 Dex Kila.
I chose this because I'm a 95% solo'ing thief. I don't have Abyssea atm. I don't really seek parties. I just solo, and do COP and Zilar missions with a friend.
I'm thinking the 6 Dex will help my TA's, and the only WS I ever use right or wrong is Dancing Edge, which DEX is a modifier.
I'm thinking the 12 accuracy along with pizza will give me plenty of accuracy on anything I'm fighting. You can see from my gear, I have a purely haste build. I never really have a problem missing. Only Kila's I debated was the DEX or AGI one, but seeing this thread made me think of the other options as well.
