The combat is tepid and below mediocre.

you're on some super-duper special loving gladiator quest/vendetta just trying to stuff on the game for probably your own enjoyment and im surprised none of this has bit you in the ass yet, although i think theres an alterior motive of personal satisfaction going on here (aka youre trolling)
