Sure, the combat feels like it has a lot of tools in the kit and you can feel like your attacks are having the right impact in most cases.
but not all class/ specs have a perfect combat feel. tab target or lock on targeting does lower the skill cap quite a bit but considering the game has to support players of every skill level that is just something that players dont have to really worry about.
from there learning mechanics, using your CDs and other tools effectively can flesh out the system. other games have action combat systems and that can feel real nice in a solo/ small group setting but once you amp it up to more than 4-5 people it becomes a mess. idk how to fix that or if any mmo has already fixed that and i just haven’t seen it.
a side scroller game like Super Smash Bros can kind of pull it off. its that extra dimension that really throws the controls out the window. Maybe Ashes of Creation will get the combination down. a mix of action and tab targeting. 
just a thought. like if wow did a combined Action and tab target system. the Action combat/ skill shots would need to deal more damage and the trade off is they could miss if you missed your shot. a hunter’s Focus Shot would feel like a logical thing that would function like a skill shot.
over all, WoW’s combat is fine though imo. system wise.
