New player seeking green class advice.

[Cathulu]

First, I regularly raid on official TLP servers. I know that the changes are quite vast and significant, so I come seeking advice.

There are two classes I regularly enjoy playing on the TLP/Modern eq, and those are Necro and Shaman. I have heard people say that Necromancers are essentially useless in raids and will have trouble finding a raid spot due to this and the fact that they are over-played.

I have heard similar about Shaman, that they are really strong, but extremely overplayed and will be rarely able to find a raid spot.

I would strongly prefer playing one of these classes, but would consider another if all of this isn't hyperbole.

What do you guys think?
