Its ffxiv combat really so slow and boring?

I'm sorry, but the only difference it does is prevent miss-clicks. If a person doesn't know about combo effects, then it means one of two things. They didn't read the tooltips, or they can't read the tooltips. In both cases we have players that will be equally sucky with and without this consolidation. Only the random miss-clicks will be affected, which occurs rarely enough for it to be of little relevance in the bigger picture.

Sorry no, you're wrong. It won't only affect misclicks. It would also reduce the demand on the player to understand their class because they won't need to understand the most basic requirement of even creating a combo because the game would do it for them. They could spam one button without realising they're doing a combo.

And you must have quite a good faith in players if you think mostly only random misclicks are why people fail combos. It's not unusual to find players who do dps as if they're completely unaware as to what a combo system is.
