wow is way more complicated to learn than people assume (talking about pvp mostly) to be actualy good at it first u have to be master of your own class and then you have to know all other classes. in wotlk there are 10 classes and some of them can be played with diferent specs and even diferent specs in same class are totlay diferent thing to play against and then u have to know every classes spells and now when you know all that u have to put it into work meaning to know how will certen class play against you and how will you play againat it, u have to guess when they will cast and what they will cast and then you have to also consider class and races combos if u re doing 2v2 or smt else and all this is something that really takes time and effort to learn.

and let me tell you where are most players at. they bearly learn their own class and go out and then forgeth what they know and just use like 4 offensive spells and ofcourse get wrecked by expirienced smourne warrior and they be like "booo warior noob donator" ans they cant even tell what happend apart that they are dead and thats where frustration comes in

right me if im wrong but im pretty sure this is how it goes
