My personal suggestions would be to check out Wildstar and Guild Wars 2. Wildstar has quite a lot of potential and Guild Wars 2 is pretty fun.
Been playing some Final Fantasy XIV right now, so far "only" reached lvl 15 as a Pugilist but I would say my reactions so far isn't great. The combat is slow and the progression doesn't feel good at all, its taken quite a lot of hours to reach lvl 15 and I only so far have three abilities to use in combat that I cycle through constantly, literally cycle, 1. 2. 3. repeat. Gonna keep playing to see if it gets any better but I don't think I will continue after the included month.
It gets pretty damn complicated once you start factoring in job abilities, and having a optimal rotation is key for high level play. I say stick with it.
The global cooldown is higher than WoW because they wanted to keep a more tactical feel that FFXI had and I appreciate it for that, especially as a healer since it makes it so I have to think more about who to heal.
