The combat system still needs a lot of work.

One counterpoint I can raise. Yes, there's a lot more fluidity in WoW's inputs. However, I feel there's no weight at all to any of the abilities in WoW. Everything goes so fast that even big hits fade into your next spam input. Combine this with very very bright coloring and effects and I can barely tell what's going on in a given fight in WoW, whereas I can usually tell what the rest of my party/raid is doing in FF14. Maybe this is just experience letting me differentiate one but not the other, but it's definitely a factor for me.

That was certainly true before Legion, but Blizzard somehow managed to add weight to the animations in the most recent expansion while maintaining the same level of speed and precision they had with the previous system. You should checkout what they did, it's pretty amazing.
