Bow would be great for the reasons listed before me, also lets those longer bow moves less likely to be interrupted if they're frozen/frostbitten.
My old Glaive I had Dual imbue, switched to ice when I couldnt straight tank. It worked wonders. PvE, you definately have an easy time between the imbue and Frost Nova. And for PvP, it would give me the ability to beat someone a bit higher then me that I would otherwise be dead by in a few hits. Also had a job war where I tanked more people then I should of thanks to Ice lol, big fan of it
