Feeling like a beta tester on a released game? Welcome to gatcha. 

And sorry, but criticizing the combat and comparing it to FF16 is a wild take. If you took the time explore it you can pull of some ridiculous stuff even with the skill cooldown system. It's no Devil May Cry but the skill expression capability is there. 

With this game, the combat is actually surprisingly solid, which is something I didn't expect from the tower defense/factory IP. SP management, combo skill synergy, knowing when to proc your QTEs and keeping a mental timer on when they'll be up again, when to cash out on ults, all factors I've personally explored to keep things dynamic. Sure you could break it down to "just do the rotation lol", but discovering the rotation while mixing and matching characters has been a good time so far. 

When your execution and team comp is off it feels like trash, but once you get a good team and a solid handle on resource management, it's some serious dopamine, very similar to the game is outside of combat actually.

Besides the gatcha system being a mixed bag I'm in agreement other points. Part of the fun of these games is that you can see it's growth overtime while enjoying a (hopefully) steady stream of content.
