Should tanks ask to do big pulls?

[Jamillion]

As a healer, I don't mind big pulls as long as the tank doesn't stop mid-pull and then run out of range of my spells. Once you stop, you need to stay there. Otherwise, you're more likely to die.

Of course there are definitely exceptions to this, in Pharos Sirius HM I chainpull after killing the giant guys down to the next pack, then again once the bomb furnace is dead to the last pack. That is one dungeon I ask first on usually.
