It's amusing when people say that PvE is completely scripted and easy. I think that most people who has that kind of an opinion has never been raiding on the cutting edge or experienced the delight and joys of being able to be one of the first to kill a really hard boss.

Vyndree pretty much hit the nail on the head with her post though. Personally, I think PvE is alot harder than PvP before the content is farmed, and sometimes a player can be much more predictable than an npc.

But thats just my 2cents ^_^
