Bungie have stated that they are looking to buff the amount of flat health which is gained via health regeneration perks such as Life Steal or Hungering Blade. A 58% increase in the amount of flat health to be exact. I had a thought that perhaps recovery should add or substract from the amount of flat health received. For instance, a player with very low Recovery would gain a flat health boost similar to what it is in its current state. However a player with high Recovery could receive upwards of 70% extra flat health. Recovery for the most part is a rather unimportant stat when specing for your Guardian. I personally feel like this would add options when choosing perks.
