I used Concentrate on basically any character that could use it. It's so ridiculously overpowered in FFTA. Especially if you use it on a gunner. Auto hit stop shots are incredible. My only exceptions were double sword for my Ninja/Thief, and the races who didn't have archers. Which, I only used a Dragoon/Glad combo and my lovely Sage/Alchemist Nu mou (edit:I think I had a Templar/WM as well. Another one just for fun though). Everything else were human/Viera/moogle. And I loved using a summoner as well. Just more when I was having fun though. Oh, and when you managed to get most of the abilities on a Blue Mage? That was pretty ridiculous. Man, I might have to go back and start playing this again.
