As someone who has been asking for PvP combos in PvE content for so many years, I certainly do not like the idea of one-button rotation WoW has implemented.

Now, you might think my statement here is contradictory, but the truth is that I prefer the PvP combos we have right now because they reduce unnecessary button bloat of combo skills (Example: 1,2,3 reduce to 1 button). This is going to free up a couple of other buttons for you to have any other skills in them (or items). Say, to have single-target basic combo at button 1, AoE basic combo at button 2, a Shield action at button 3, and so on.

If we have everything in one or two buttons, that'd be just too much. It's the extreme that I don't want to see in any video games.

Of course, I'm speaking here from my experience playing ESO and GW2, in which the entire hotbar is around ten buttons, but still has enough depth to make it engaging and interesting, which is what I'd like to see.
