Heya! I've made a build that uses 3 ground AoEs that do heavy snare, alongside with Barrage of Frost with Frost enchant on Charged trait - making immobilizes every 4s, while my front bar hits through dodge and can pull opponents back into AoE stacks.

Totally unplanned and unexpected part of the build is how resilient it is with backbar ice stack blockheals, given that resource wasted to blockheal is the same resource that is restored during heavy attacking.
