Caster (ench) raid resist gear?

[Goregasmic]

I don't want to argue over semantics but I'm not sure it breaks, pretty sure it just gets wiped because I did a couple tries of fetter on tashed and green trash and it never held, when it otherwise rarely breaks. Not sure if it is a root or debuff thing to prevent people logging onto another toon and benefit from debuffs. IIRC it holds when zoning (snaring near zoneline and zoneing out/in to split) but on camp, not sure.
