Cheers for the advice, guys.
In the Wii original, I was level 89 when I finished the game, but here it looks like I'll finish the game far sooner.
I confess, I've never been much good with the finer nuances of the combat system like customizing soul voices, so I tend to brute force my way through bosses by overlevelling.
Currently maining Samurai Gunner, because holy crap topple + flame grenade is crazy powerful once you max out the latter.
