Most of my opinions now foor WoW after playing hardcore for about 2 years is it is boring, and most of the same stuff.
I play a paladin named Ezareth on Frostmane. For a good year and a half all the way from MC to Naxx to Black Temple I have done endgame with a guild called Paradigm. I recently quit since counter-strike I found was much better but I do aggree with you, the game takes up more time than anything else. You spend a good month leveling give or take. Then to PvP you have to train or play your class right.
When you go into endgame the game gets fun for a little while until the part where you run it for a good month and your sick and tired of it. In PvP I would rather do even though I was an epic'd out holy paladin in tier 4 and tier5 was fun for a while until the part where I couldn't kill much being holy (unless I heal them to death

) so that didn't work out too well.
Blizzard changes that game constantly to try and keep a way for the gamers addicted so to speak and also keep their opinions and suggestions to give them what they think sounds good. If someone suggests something really nice, it more than likely will come out in the expansion. THe burning crusade for instance, released the story of Illidan (like from the warcraft games) and put him in one of the instances.
I can only imagine when the next expansion comes out, when they release Arthas (which they may have done too soon since he is a main evil doer) and it will be the same thing that you will see like BC but with a few twists so I mean nothing new will change except you go in the instance, pwn some guy and get some loot and do that for a month. I quit just because it got so boring, it wasn't worth the money. I still recommend the game since it is good, I just refuse to play it.
That is my opinion on WoW. I am looking forward to see if anyone else here plays it since most of spawnpoint shuns MMO's altogether.
