Its much better understanding

Its much better understanding who you have time to heal, and who needs to be healed up immediately rather than always bombing everyone to 100% whether it be pvp or pve. Currently in both if someone isn't at 100%, they're effectively in killing range whether its because pve burst damage is so insane because that's the only way to wow gold fr challenge healers or in pvp because you can get cc'ed for 20 seconds or more in a single stretch by the right comp and there's nothing you can do about it. Its actually much less stressful on a newer/less experienced healer if they know that jimmy sitting at 60% won't drop dead in the next global because he decided to heal johnny who's sitting at 55% or even healed joe at 70% because he was standing in poo.
