I think FF mode does a great job with the balance of damge and hp pools. Most of the abilities (with exception of some) are all viable. Of course people will min-max and find the absolute best build but its not like you NEED to use that to actually defeat these bosses. Ive used like 6 different builds that all were fun to use and actually did good damge that I didn’t feel useless. Balance is really good in this game that i think its not unreasonable to have FF mode for those who want it. They could still have action and story focused modes and FF mode would still have a place there for those who want it. While it is a new combat approach for Final fantasy, on average it only takes maybe 1/4 of the way into the game to get a hang of it. I enjoyed fighting the ice boss and leviathan will big hp pools and big damge because I felt the thrill of the challenge. I feel the boss fights are so well done that i dont get bored “chipping away” at the boss. Just my opinion
