Its ffxiv combat really so slow and boring?

Eh, but the single tap is also vulnerable to fat fingering it.

Everything is vulnerable to fatfingering. I fatfingered displacement and killed myself when I meant to hit corps-a-corps more times than I care to count.

And you're also needing to deal with muscle memory, so it doesn't work well unless you can map abilities in a manner.

AKA: Practice.

you are still dealing with a decent learning curve, both in configuring your layout and triaging abilities, and there still is reaction time penalty, so it's best anyways to reserve it for macros or uncommonly used stuff.

I'm glad we agree it's easy to access more than 32 abilities. Yes there's a learning curve, but it's a curve worth exploring, practicing, and mastering rather than begging for button consolidation.
