There are a lot of joys in playing World of Warcraft. You may meet friends from all over the world. Besides, gearing up is never over, like rep farming, because you get so little time to enjoy your new tier set.

The hard grinds (rep) are Molten Core and those related to the Insane achievement. They are also pointless (ravenholdt or shendralar)

I buy wow gold and cheap wow gold when I enjoying the raidings. About ICC being easy – I know a kid who plays wow, he is 12 yrs old, he has a level 60 hunter and a level 80 dk. He is clueless about playing in a raid, he does not have gems or enchants, not even cheap ones, yet he was doing Dreamwalker in 25 man some days ago. He leveled to 80 using his starting area gear plus some random drops, whithout doing quests and stuff, so he knows almost nothing about wow. However, he got in ICC 25 man :)

Imo, polishing a char is better because like in real life, learning a job is easy, but mastering it is not, and usually people tend to admire polished things and their creators, not the apprentices. Sure, wow gold (ie: World of Warcraft Gold) and rl are different things, that is why people have different approaches in wow.

I think you are a kind of person that enjoys the road more than the destination since you move so quickly from one thing to an other (which is not something bad).
