the %1 for two people usually meant you and one other in melee, and if it healed you, you spread that healing to others at a smaller rate, but it was still healing, plus add in you 2 concreates if you slated that to heal along with your auto attack that healed, you do alot of melee healing. so it was more of a stack on melee healing.
My damage is crabstatic, but it was more for do damage to heal then anything else style they had. concept was great, but wasnt quite there yet.
