I soloed it on all 3. Starting with my hunter. Got it to drop on my warlock which was my last run. So happy to finally get one. Doubt il use it but it's there and that's all that matters haha I think you have the best chance at these specific drops if you run on a different character to the one you are farming the gear for. Iv had the titan arms twice while playing on my hunter. As well as the undying mind mark and the warlock helm from the giant shank twice. All from playing my hunter. Bungies way of making people make 3 characters
