For whm Regen will be your friend, Divine Seal regen will be your BEST friend. You should be noticing how effective cure is on a tank, seeing how much it heals him. If it's healing him for 30% and he drops to 60% consider using Cure II if you think you won't be able to save him with 2 cures. Single Target Healing gives a .5 second window to cushion weaving ogcd so use that to pop Presence of Mind to help catch up. If you don't already have Swiftcast, get it. At learning levels it is an Emergency Healing CD. It continues to be later, but there are better options and it becomes a last resort. Dabble into cleric stance when you're comfortable to push your experience with emergency CD/Non-Emergency and recovery while speeding up the run. Assigning an assist key (I use L3) will help with that. Don't stress out and have fun. xD
