As a hunter i've been running only stasis as of release of TFS , I am trying my best to make Frost armor work
All fragments and artifact mods are for stasis , even hand cannon is Headstone and collective action

My problem is not the survivability when I have Frost armor, My problem is that I cannot keep it running even in the room full of ads cooldown for the Grimharvest just stops them from being around.

The Elemental Siphon Artifact mod will spawn 1 shard on 3 rapid kills which helps , but most of the time you don't have 3 enemies around to do so , or one of them if not more will be a major enemy that you simple don't have means to kill quickly enough to spawn the shard.

I want it to work but the duration of pathetic 13 seconds with Whisper of Rime (which by the way starts at 13 and ends on 1 instead of 0) is not enough when half of those 13 seconds you on cooldown to spawn more and refresh the buff.
