ENC, SHM, or SHD?

[highelves can't dunk]

First off, server ruleset is badass. Praise Emp. Rogean etc. Hope the crying from blues in the beta doesn't get anything changed.

So, I'm considering playing an enchanter, shaman or shadowknight when the server goes live. I played a lot of vallon/sullon and a bit of rallos, but mostly as a necro and paladin.

I'm leaning toward ench as my top choice, but I'm curious about a couple things:

1. Do charmed pets take any exp. from a kill if I hit the mob?

2. Is charm useless now? I read a lot about nerfs and it sounds like it might be.

3. In high-level pvp, assuming most competent players have high magic resistance, do enchanter crowd control spells ever land? If not, would I just be a buff bot? Or is fighting using a charmed mob at all possible? (obviously very dangerous)

Second choice would be shadowknight, however the exp. penalty sounds pretty massive, like 65% or so for an ogre sk. Is it really that bad? I've got some friends who I'll be leveling with, and it would suck to have to kill 2 extra mobs solo for every 3 mobs we kill together in a group just to stick with them.

And third is shaman, no real questions here except one: Is AoN available on release? Obviously I won't get into PoF for a long time, but technically, is it able to drop right away or will there need to be a patch? It would be nice to not be a fatty forever.

Sorry for another "which class should I play?" post, but any answers are appreciated.
