They stand in fire, gas clouds, and various other nasties on the ground. They can’t do the slime dance, or make the jump to Thaddius in Naxxramas, and you just know that they are going to forget to turn around when Eadric the Pure casts his Radiance. Never mind that a huge warning goes across your screen.
  I’m sure that these players do not feel they are in the wrong. Nor do I think that they are failing in this way to be malicious. In fact I’m sure that there are those out there (these face rollers included) that would defend them Maybe pulling out the excuse they are casual players, who don’t have a lot of time, and therefore we should go easy on them. But I think that this excuse is nothing short of a load of Tauren dung.
  The old casual player excuse kills me. Mostly because in the last expansions and patches Blizzard has made WoW much more accessible to the casual player. However WoW is never going to be a game where you can just hop on and play. You are going to have to do some work beforehand. The grind, the farming, and other preparations are as much a part of the game as any instance.
  “But I don’t have time to sit and read a lengthy strategy, or watch some corny video. Can’t I just figure it out as I go?” No, you really can’t . If you don’t have the time to sit and read up on the fights you will be encountering then in my opinion you have no business trying to do instances. Stick to single player and save me and the rest of the population the headache.
  At the very least download some boss mods, speak to some people with more experience than you and get a general idea of what you are up against. Even mastering the most basic rule of WoW (never, ever stand in anything unless otherwise instructed) will save you much embarrassment and give the impression that you at least have some idea of what you are doing. Keep in mind, if you are dead, you are useless.
  How exactly these players fail so hard I have no idea. Even if you haven’t read the strategy on a fight, shouldn’t it be obvious that you should move out of the huge green gas puddle, or rather large patch of fire you are currently standing in? Even if you manage to miss these things, shouldn’t you notice that your health is dropping rather quickly? Or maybe after the first time, you should realize that you did something wrong and attempt to not repeat the mistake?
  Let’s say you manage to miss all these things any player with boss mods (and every player should really have them) should get ample warning that they are doing something they shouldn’t be doing. Most boss mods will go crazy, making your screen shake, blasting loud annoying noises, and popping a huge warning across your screen. Yet some players still manage to fail in spite of all this.
  I do realize that not every single player is going to be an amazing player. But if my 4 year old could possibly play better than you and die less then perhaps you need to reevaluate what you are doing. It may even be time to choose another game, because WoW is never going to be a game where you don’t have to pay attention.
