And a battle res and normal res are also forms of healing. And to that effect using a defensive spell, potion, healthstone or kiting, those are also forms of damage.
Say an enemy has a big nasty spell that does a ton of AOE damage which cannot be CC’d or interrupted, if there is not much damage going out prior to this AOE than the healer has nothing to do, right? They sit around waiting for the AOE to go off and then be an Avenger and heal the damage.
But why not be a Prevenger and help kill the enemy before the damage goes off and forces you to do some healing? Would you rather just sit around like a tree trunk and be a reactive healer? Or is it better to help kill the enemy before they have a chance to try and kill your group?
What about interrupting? Do you no damage healers also refuse to interrupt, stun, CC or generally try and stop enemies from damaging your group to begin with? Isn’t it better if you can stop an enemy from damaging your group in the first place rather than need to pop off 6 flash heals to top up the group.
Killing an enemy before they put out damage is effective HPS because you are stopping the need to even do the healing to begin with.
Letting a DPS die who has 4 stacks of grievous or some nasty dots and is low health is in the same vein, by letting the DPS die you can focus on keeping the tank alive, which means the rest of the group won’t get whacked, thus meaning they can be given the best chance to kill the enemies and stop a total wipe and a bigger waste of time.
Yes, letting someone die is an effective healing strategy.
And at the same time for you DPS and tanks, pulling more, only using DPS spells because ‘mAh DaMaGe’ can generally mean less damage is actually being done and therefore more healing is needed, higher chance of wiping, higher chance of wasting time.
If you, all of you, healers included, can interrupt and enemy, CC someone, pop a defensive, take 0.3 seconds to move 2 foot right and help each other stay alive and kill the enemy before they kill you, it’s ALL a form of healing and DPS. Because if your group gets hit by something that kills players when the healer could have put a 2K DPS and killed them first, or the DPS could have used a potion or a defensive to stay alive, then you are all to blame for wiping and wasting more time than is needed.
Taking 2 seconds to stop casting your chaos bolt to move from the frontal or AOE to stay alive is far better to have lost your cast and 2 seconds than it is to get hit and die and lose 10, 20, 30 seconds while you get a resurrection or run back and effectively waste everyone’s time.
