Questions about overhealing

[Wyyote]

So prove it. I've looked into this rumor and found nothing to support it. It's almost impossible to test, there is no official response that I can find, and it doesn't feel like double agro when I'm healing. It also makes no sense. Overheal is already punished by wasted mana and needless threat, why make it even more punishing?

I'm inclined to agree. The over healing, aside from being sloppy technique is an aggro magnet, and MP black hole. In general, it's bad news. In terms of how bad I'd say it's based on content. In WP, who cares. In Titan or coil, it literally could wipe the party.

I havent done any reseasrch about Regen. but it doesnt took long to me to figured out that regen UP, aggro everything that the Tank didnot claim when he pull.

As far as I've understood it, all heals pulse aggro from the person healed where the aggro is assigned to the healer. So for every tick of regen, a pulse of enmity is assigned to the white mage. If the tank is too slow to pull AoE aggro before or between ticks, the mobs will aggro the healer, even if the actual value is low.

So far I haven't found any indicators or parser tools for overhealing, which is a damn shame. How do people research aggro amounts for heals? Are there numbers anywhere you can check or do you wing it with the aggro bars on the party list?
