So Valithria Dreamwalker is now active in Icecrown Citadel. It's an interesting boss, where the healers have to heal the dragon up to full health, while the rest of the raid deals with adds trying to prevent this.
It's a pretty good fight, but there's one aspect of the fight that I do not like.
Every so often, Dreamwalker will create portals to a dream world. In the dream world are little orbs that you can touch and it will give you a stacking buff that increases your healing by 10% per stack.
It's possible to carry your stack from portal to portal, but the timing is exceptionally tight. If you are capable of carrying stacks, your healing gets massively magnified. If you're not, or have high latency, your healing is greatly hurt.
The timing is way too tight for the potential gain. If healers are meant to carry the stack from portal to portal, the timing should be slightly longer. Alternatively the penalty could be less severe, maybe losing a stack per second instead of all of them at once. If healers are not meant to carry stacks, the timer should be lower, so the stacks drop off before you enter the portal.
Basically, if Patricia is a little bit better than Daisy, Patricia should do a little more damage or healing than Daisy. You shouldn't have a situation where Patricia can all of a sudden do twice as much damage or healing as Daisy. Small differences in skill should not translate into very large differences in effectiveness.
