I guess I should submit two additional entries for Rangers
Me and my best friend, will both probably roll Rangers when Aion is released/entered beta. I remember the Ranger in EverQuest. Originally, they were pis* poor, something weaker than rogues, but later one, when they were buffed as far as with their bow skill, it was awesome.
Always loved how they killed stuff from afar, kiting and sniping all included
Nothing like the skill of killing a monster while circling/going inbetween pathways of others
As far as WoW Hunter goes, yeah.. range sure is a benefit. I know a lot of people will roll Assasins, just like Age of Conan, majority of beta players will be Assasins, which is kind of sad. As if other classes don't deserve some attention.
One thing is certain. Aion will need tanks&healers just as much as any other MMO game does.
