Healing Breath 4 might be a bit strong. Currently with every piece of Healing Breath potency gear available to DRG, my healing breath does 601. That's 601 HP every 60 seconds at the cost of nothing except having my Wyvern alive. That's in essence a hateless/non interruptable and free Cure V. With Deep Breathing fully meritted, I can cure well over 1k HP every 5minutes. I dare say that if Healing Breath IV is significantly stronger, we may be entrenching on other healing job's territory as a DRG/RDM right now in Abyssea with HP atmas can dish out 900-1k healing breaths without Deep Breathing on players in range under 50% HP(this is more...way more than poor RDM or SCH can heal). If Healing Breath IV is going to heal 800+ with the gear I have now plus any new gear that enhances Healing Breath more, plus Wyvern HP bonus from level ups, it might be a wee bit overpowered, especially for solo. Compared to DNC that spends 80%+TP to heal themselves for 800 or WHMs that spend 150+MP. Perhaps instead of adding Healing Breath IV, reduce the recast of Restoring Breath to maybe 45 or 30 seconds?
