They really should increase the Recovery cap for all healing potion to about 3-4 times the current cap, at level 60 most non-tanks will already have 10k HP so healing 2000+ with each X-potion every 2 minutes isn't so overpowered when healers are already healing much more every few seconds. Besides it helps a little for non-healers to try to solo something on the map (like FATE or hunt for example).
