My friends and I got to talking about Destiny 2, and if an Ice/Frost based subclass should be added to compliment the already existing elements? I believe so, as water and ice elements are my favorite and so it is for many others. Hopefully this idea can work it's way to Bungie HQ. I imagine frost spells/supers/grenades freezing opponents, enemy grenades, and even deflecting bullets with frozen barricades. I imagine slowing down opponents with your skills. Imagine a super where you freeze your opponent? Orgasmic. Imagine a grenade that launches icicles in every direction? Imagine throwing an icicle as a melee attack and causing bleeding damage? Possibilities my friends! Edit: there is no argument supported by the grimoire which prevents a water element subclass from existing in this sci-fi high fantasy shooter with unlimited potential to evolve and add onto.
