Earthly Star deals damage as well, and not small amount of it either. Not casting it at the beginning of battle just wastes damage. By the time you'll need it for healing it's going to be off cooldown anyway.

As for the initial post, the person specifically said "group of mobs", so it certainly was not a boss. The tanks should not have a reason to wait for the entire 20 seconds. 20 seconds is way more than enough for everyone to come to the spot and get ready to fight fodder. Granted that using Earthly Star preemptively offers greater damage potential overall, the healer did nothing wrong...except in assuming the tanks would do their basic job.

Of course, that's going by the assumption that no one used the alliance chat to say they will be back soon.

Healers being near the tank or not is irrelevant. Healing (including heal over time) generates aggro near the person healed. Normally that's going to be a tank, hence why healer will usually get aggro. But at that point, the healer will get that aggro even from the other side of the dungeon.
