I believe the recovery, mobility and resilience doesn't work correctly ill be showing an example below, it would be nice if Bungie could take a loot at this.
My Warlock is wearing:
Philomath Cover Helmet - 4 Recovery
Philomath Gloves - 3 Recovery
Philomath Robes - 3 Recovery
Transversive Steps - 2 Recovery
These Equal 12 Recovery then add the Restorative Warlock Armor Perk and it should be at about 12-15 Recovery, yes i know it caps at 10, however my warlock only has 9 Recovery, so there really is something wrong with this.
