Okay, I can see where you are all taking this but I feel that a paragon type class could make a return. It was purely a support class that i think could make a return. It relied fully on shouts. Their is no class in the game that I think is purly support in that way. Yes, you might be able to contest a warrior can do that or possibly a gaurdian. I just genuinly loved the class.
But considering how the original guild wars expantions came with pairs of new classes I think they might be able to work it in with suggest martial arts monk. An un-armed combat class would be cool. Equipping weapons just for character stats. Such as making them capable of carrying warhorns and idols over physical damage weapons. Heck, I could see a protection support class monk wielding a shield in mainhand and a focus in the off but only commiting to Hand-Hand combat. Thats an amazing idea.
