Sigh... Most MMORPG's require skill to some extent. I've played end-game wow going into T6 content. You can tell when there is someone who absolutely dumb. The entire raid WILL DIE.
You can't say WoW doesn't take leadership or organizational skills. Have you ever tried managing a guild of 100-300 people, making sure there are enough raid spots for everyone, and that no one gets really mad and leaves? Or else organizing 25 people into a coherent force so that they work as an effective machine? I haven't, but from what I've seen it looks pretty damn hard.
There are no unbiased opinions, whether you play them or not. Even if you play MMORPG's devoutly, you can still think they take no skill. Example: I play shooters, I'm pretty good at them, I think they don't take much skill besides quick reaction, spatial intelligence, and situational/strategic awareness. I find them easy, whereas someone who is not as skilled marvels at my amazing feats of headshotty goodness. =P
MMORPEGERS usually have very low level entry points and not an incredibly high learning curve. It is a basic business formulae. Make the game as accessible to everyone as you can, while offering LOTS of extra content to those who wish to pursue it. WoW had to have something to it to be able to build such a large player base, it didn't start with however many million people...
This is almost the same indignation PC shooter players felt at the release of the console. They feel a condescension towards console players, and their lack of skill, much as many people feel a condescension towards MMORPG's because they too do not graps some of the skills required.
Every type of game can be boiled down the same way as people do MMORPG's, thus proving they too require no skill:
Shooters: Point and click and someone dies. Run around shooting things.
RTS: Make ressources, make units, kill the other guy.
Fighter: Mash the attack button 'till the other guy dies.
However, I believe everyone who plays these games beyond a basic level will argue that I am dead wrong, that the game is deeper than that, and that it does require skill!
"That game is not the simple atrocity you are trying to make it Sir! That is only a very shallow overview of some of the basics of that type of game, I am outraged!". you say.
And thus I make my point.
