Late Game (Including Velious) Class Roles

[Kajaen]

Hello, I poked around a bit in the forums today looking for an answer to this question and found a few related threads, but they were all 2-3 years old and there seemed to be a lot of disagreement. My question is this, what are the various class roles at 55+ once Velious is out?

The reason why I'm asking is twofold. One, there seem to be a lot of certain classes, like Monk and Shaman, and everything that I've read about these two classes is that they maintain their high-level usefulness. Enchanters, on the other hand, seem to lose a lot of their usefulness at high levels due to mobs with a high MR score.

So, what is your opinion on the classes? I am currently enjoying the hell out of my paladin, but I want to start a secondary character that is a bit more soloable for off hours or when I feel like playing on my own. I'd prefer to avoid another hybrid class, even though the Shadowknight drew my eye, and was looking at the Necromancer, but wanted to get the opinion of the forum.
