Which Ua should I make for the Union/Justice revamps? Hey peeps. I'm in a spot. I'm going to make a UA very soon, but I'm gonna train it after one of the revamps (depends on the class) My choices are these. 1: Paladin (Soul Driver seems like it could be useful) I/L Arch Mage (sorta iffy about Flame Gear) Buccaneer (Shark Wave seems like it would be useless with the new beam move) Shadower (I don't really have an opinion on Vampire) Bow Master (Wind Piercing seems nice) So what's your opinion guys? Which one would be the most useful?
