It feels to me that ultimate costs dot fit any balance for now neither in terms of cost/dmg ratio or cost/utility.
of course some are cheeper than others, but when you take a quick look at them it's so random that it cant have been oversight yet.
maybe the time as come to check that?
i'm asking those question because i think that the next arena to come could alter them ultimate now that each basic weapon skill have had its own arena weapon, and before thinking of adding a weapon altering ultimate, it could be interesting to finally have a look at them ultimate. by that i dont mean puting some freaking hated castime on them but yeah, a fair one for once..
