Ok few bold areas there I would like to clear up. Cetra isnt even in the runnings for best war in ballista, and last time I remembered he said it also. Im not going to get into detail for why he isnt unless someone ask.
Shuto on the other hand is not even close being called a decent mnk in ballista, he is a coward and will run from anyone without his entire team. He has his own ballista ls (ballista company), and has been challenged by the Deathdealers in a 6 vs 6 match, but only says {no thanks}.
The thing about not meeting many more drks, do you go to normal ballista? I havent been to a ballista yet where there isnt at least 2 drk/nins and a drk/mage.
Other then that list is good.
Well, I dunno of any other WAR that did more decent against me so far

This is as far as I see it, I mean, tell me some other WAR's that are good, I'll gladly edit them in =P
And about Shuto, I did see him several times in the high ranks, thats the reason I added him in really, I dont know much about him, but apparently you do, so, I'll take your advice for it =P Thats the reason I put him in though
And yes, I do go to normal ballistas, I never been in a 40 cap, did a few 30 caps, and I did around four 50 caps, so counting about...less than 20 ballistas all my life.

Yes, you could say I'm still a bit of a newbie
