I haven't read all the posts in this thread just throwing in my thoughts.
Even after post nerf, mesmer is still good/strong class to play. it just has to be done a bit differently. I dont know where you got the idea that they're a poor class.
Rit is a little bit better post-nerf, but not much, yay we have quick casting spirits. they still die quick. spawning is still garbage, oh wow +4%? all of the good weapon spells only last for a few hits. so the duration doesnt matter, and the one's that didnt run out in a few hits, lasted long enough already.
but 600 rits, in my opinion, are the best 600 class. VwK ftfw! although they lack native spell denial (spell breaker) this is very easily maintained by a hero/friend. 600 rit's are amazingly faster than 600 monks. the life stealing is amazing. My monk has been highly neglected since i started using my rit too 600. the only time i use my monk for 600'ing is when i need to do a Zquest on him.
