they could make it enemy dependent to have some variety so at least it changes from combat to combat depending on enemies ? At least that way the barks are not always the same throughout the game. You could have 'generic' class, character depended bark and throw in some 'enemy' triggered barks too.
Eg. Astarion fights goblins: eat that you little creep , SH fights intelect devourers: 'ugh, these things are disgusting' , gale fights caster: 'you call that magic ? I'll show you how it's done, barb fights goblins: 'Ah I love the sound these make when you smash em' .
