Solo? Party? Raid? There is no blanket statement here. Being a raid dps takes no skill at all under a "WoW" sort of system (not that it orginated there but whatever). You know what you do? Spam your skills in a practiced predetermined rotation while a cpl raid healers keep your hp up. Skill? Laughable. If danger comes guess what? You can run away! The only skills required in this situation are finger dexterity and knowing when to run away. Even tho, most ppl dont even bother running in those situations...thats the normal culture.
If you're a mage its the same thing, spam spam spam in a predetermined rotation. Tank? Spam spam spam in a predetermined rotation. The only two classes that really face difficulties in that situation are healers and tanks, due to the sheer amount of finger dexterity required to keep up with everything. Other than that its a joke. Unless you're a healer, or *maybe* a tank, all you need to do is press buttons as fast as you can to run up parser. Pvp? Same thing. I press my buttons faster than you I win, unless your gear is way more OP than mine. Because things move so fast there's very little time for strategy, since it is over within a few seconds anyway. Generally speaking, gear being equal, first hit wins almost every time, not counting class advantages.
