I can understand where you're coming from as I also like to play MOBA games.
It just doesn't factor in to my evaluation of the combat system as a whole, sure it "slows down" combat in a way, but it fits in the context of how the rotations work and just the general combat flow. You might like a game like TERA more for its combat (not saying you should play it, it has its flaws), if I'm to guess.
I've accepted the bad with all the good. I'm doing the same, attempting to just get used to it and ignore my feelings of discontent on the subject. I still love the game I just wish all the characters didn't talk with jargon...
I struggle to do what you have already done.
