Vex-Ohm-Ist-Dol is Exile IIRC. Thats 2 HR's and an Ist.
The only reason I see for glitching an eth shield, is for Exile. If I was going to use 2 HR's for Exile, I would most certainly make sure to have an eth elite shield with 40+ res.
I really don't see the need to use an eth shield at all unless you make an Exile in it, or plan on Zod'ing it. You could, I suppose, use until it breaks as a Rhyme Spirit or the likes, but I wouldn't see the point.
So basically, I say it is not worth it.
