Prepulling mobs as healer

[Nedkel]

I wont comment on 'you' but the 'other' players, in general, I'll disagree with.
The idea of multiple pulls is to speed up the run but in reality it's the opposite in most situations.
Healer Damage
While a regen might be enough to keep the group alive it does allow the healer to damage too. Considering they are 25% or the party that holy spam or what ever spell is used is fairly signifiant. And the short stun means no damage or abilities for the party to dodge. A damage increase, depending on what job is doing the AoE, more packs may not be optimal for them so they chip away at the packs rather than doing even damage to them - taking longer.
More dodging
There's also AoE dodging . Depending on what mobs there are there might be large amounts of AoE and adding a new pack would mean you spend more time dodging AoE than you can doing damage. Sure the healer might be able to heal through it but then they can't damage.
And those tanks - chain pulling
There's also the pre-pulls - wait by the barrier to pull faster. That's not making something faster. If you move at pack at 20% to move to the barrier you're making it hard for damage dealers to attack the pack so they have to stop while you take the pack for walkies - wasting buffs, cooldowns and procs. Less damage.
MMO players in general are good at the How - what buttons to press - but not why it's done. Speed pulls are one of those situations, where multiple pulls have disadvantages but because the why is not understood it's done all the time, often to the detriment of the group.

Its not the opposite its simple math.
If you have 2 groups with 8 mobs in it you are far better of pull all of them instead of 1.

DPS job could do twice or more damage as tank or healer, and because of that tanks and healer damage does not matter all that much. Them working harder have little to no impact on the speed, even if healer does half of the damage he would do with single pack you effectively double the damage done by DPS classes when pulling twice as much mobs making things go way faster thats it its simple math.
Fastest run in the world are always wall to wall pulls.
