I know I feel like cover is more handicap than help but I'm trying to figure out if there is something I'm missing. I don't actually know how our defensive abilities stack up to other classes. I don't know if while in cover we do MORE damage than any other class. I suspect, but I don't know.
I'd like to add though that while we're the only class that can't be interrupted by interrupts, I believe we're the only class that CAN be interrupted by roots and snares.
