The combat gets better, FFXIV has a massive issue of most classes only playing the way they’re supposed to on max level. I guess that’s common for many MMOs, but it’s especially bad here imo. I also stopped playing during Endwalker, so I don’t know what’s been revamped since then.
Even if they’ve continued to simplify and homogenise the classes, the dungeons and raids will get better. Once you get into the expansions you’ll start having more fun mechanics to play around.
