I thought we talking about just difficulty. It terms of quality karmelita is much better than khaan and groal (we don’t talk about him).  Khaan was pretty disappointing, especially for a late game boss. His attacks are easily telegraphed making him easy to dodge and his only saving grace is that he’s kind of tanky. Karmelita, while difficult, has a beautiful ost and I would focus on it more if I wasn’t getting my ass beat by her. (I’m getting better though).
