Caster (ench) raid resist gear?

[Goregasmic]

So I'm starting to be close to getting all the EC pieces I want and I'll get some SS MQs too for my "all around" gear set. Eventually I'll be ready to join a guild and raid some. I'll have to come up with a solid resist gear set too.

As an ench will they even let me raid as an ench? Outside C2/haste bitch from what I understand there's very little to do if you can't charm anything worthwhile. Do I really need to be within AE range as a chanter? From what I understand our nukes are mostly resisted due to the stun component and shamans have a better slow.

I never bothered with VOG because I just don't need it, I mostly solo. Do guilds have copies of that or it is critical I shell out the 12k for it?

And then what's the magic resist numbers to aim for unbuffed?

From what I understand the most critical is MR, then FR/CR, then PR/DR? How big of a deal is pr/dr? I noticed on most pieces it is either cr/fr or pr/dr, svALL being pretty rare.

Any other ench raiding advice is welcome.

Thanks.
