well 99% of what rogues do they dont do because they make a decision. its because they know that if X player is casting X spell click button Y. I have about 50 keybinds on my rdruid, probs 60 on my UH. doesnt mean they take more skill im afraid. Its a retarded statement because having focus macros for everyspell in ur spellbook doesnt make ur class take more skill. And its common knowledge that UH dks have way more keybinds then rogues in most cases.
Having more keybinds =/= more buttons to decide inbetween.
If I am casting roar of sacrifice on a teammate, and I have three macros for it, one for each person.. is it really a decision? No, I cast it on the person that is taking the damage. The only real decision is to cast it or not cast it, and that is where the skill comes in.
Is it better to give him roar of sacrifice, or is it better to scatter shot the guy attacking him? Or maybe I could simply give him freedom and snare the guy attacking. Maybe I would want to shoot a snake trap to root them, or maybe the enemies overzealous attempts to snatch a victory by killing my teammate who is obviously in trouble put him in a bad position and the best thing I could do is use my superawesomeamazinghunterdpsaimedpyroambushmoonblastshot to turn it around and kill him instead of actually attempting to save my teammate.
And what is it simply? It comes down to simply pressing buttons. Unless you do more than read what people literally type and don't think it out, you won't understand.
Those decisions are what makes a player skilled. A class with a lower "skill cap" as it were would have less options to choose from.
If I have to choose to use a scatter shot to save a teammate, I do so in the knowledge that it will be more difficult, if not impossible to CC an opponent until the cooldown comes back. However, it could mean that it saves my teammates life.
A mage, on the other hand, is like "Oh, look. My teammate is in trouble, maybe I should freeze them... lets see, which of my 8 roots are currently off cooldown? Oh, whatever, I'll just press the random button."
Obviously that is an exaggeration, but I hope you are smart enough to see the point I made.
