Its ffxiv combat really so slow and boring?

It's actually more like 111, 222, 333, with oGCDs throw in between and whatever other abilities you have. The current system we have now doesn't require any more thought into it than the pvp combos do, they just require more buttons. Before you've pressed your 1, 2, or 3, you already predetermined what your second and third button presses are going to be.

I don't know if I would go that far, I mean it really depends on the class/job in XIV and there are things like random procs in some of them, such as Firestarter and Thundercloud. And the rotations tend to be complex enough that you have to actually keep track of where you were (or use the job gauge), unless you get so ridiculously good that you don't even have to think about it... but most average people aren't like That though.
