How the skill ceiling? Is it complicated or requires skill kinda like a DMC game, or is it just chaning abilities without worrying too much about dodging, attacking, etc?
It's an action RPG essentially, so you don't need DMC fast style reactions, but you do need to know when to block and dodge, while knowing what skills to chain together. Tifa is a little bit more action-y, as is the Yuffie DLC, but you should be able to get through it without DMC skills, there aren't any like, complicated combos or anything.
That being said, as far as skill ceiling itself, you can absolutely make it look DMC-ish at times once you understand the combat, there's some crazy shit on youtube
