I agree that many weapon sets and utility skills have long CDs and as such become very situational and so in normal fights your mostly using "skill 1" and one other skill on CDs while the rest you use situationaly.
But I would also disagree of lack of button "pushing" at the same time. Wait, how can I agree that you are not using many skills yet disagree with amount of button pushing? Simple in games like (for your example) WoW you have more spell options at any given time and most of which do not have CDs, but for the most part unless a green/purple puddle is under you all you press as far as buttons go is spells. While as here you may have less spells at your disposal with 10-60 second CD on each you are constantly having to keep positioning with moving and dodging and kiting, so while your fingers may not be as busy up in the 1 through 0 range of your keyboard (or your key binding equivalent) they are constantly having to be used for "wasd" keys and v (again depending on your key bindings).
Point is just because your not constantly having to spam skills you are being just as much active via having to keep on the move and it is much more reaction based rather then rotation based and so though it may be technically less keystrokes since you can constantly hold down the straif key it does take more effort into paying attention and not just getting to fight A and going "ok I am going to press 1,1,1,2,1,3,1,1,1,2,1,3,1,1,1,2,1,3, move 3 inches left, 1,1,1,2,1,3,1,1,1,2..." to win, its "ok I am going to auto attack, every time I get a chance to bleed I will cast that on CD, every time the enemy starts getting to close to me I will snare if its not on CD, if it is on CD then Ill use blind instead untill my snare is off CD, and make sure to apply volnerability whenever I am about to burn all my damage dealing CDs to do 10% more damage on those CDs while at the same time constantly straifing and occasionally dodging to not get killed in 2 hits"
Its just a different play style game, one is heavy on casting a lot of spells quickly but all but ignores positioning outside of the occasional step out of the fire, while the other is heavy on positioning and light on the using spells outside of situational circumstances. Both your doing about the same amount of work but one or the other will feel like more work which is highly subjective. Me personally I find the keeping position more engaging then hiting the same spell rotation over and over, but like I said that is subjective.
