Good day.
I found that the 105 Orkham accessory set for healers is the only one that does not have a bonus to stamina. It turns out that all classes get 3 bonuses for 3 items, and healers only get 2:
I think this is unfair and suggest adding a 3rd bonus to stamina for the accessory set for healers, at a minimum of 8%.
I hope this will be added to the game =)
