When an exotic heals for less than the Recuperation armour mod, that's a good sign it needs a buff, especially when that's the only thing it does. Obviously it needs to maintain the same healing value in PvP, but in PvE it needs a significant buff to be useful. One thing they could do is change the healing to Cure, and have it give Cure x1 in PvP, and Cure x2 in PvE. If it's not possible to split the Cure amounts between game modes, then they could have it provide damage resistance instead, or Restoration, which I'm pretty sure can have different durations between game modes, or maybe even overshield, which we know can be heavily nerfed for PvP. Whatever the case, it needs something done to make it not just a PvP exclusive exotic.
