As someone who likes tanking dungeons I've noticed a trend, at least on Materia, of DPS and Healers deciding to pull.

This can be in the form of using a ranged attack on an enemy I haven't reached yet (waiting to get into melee range for an AoE). Or if I pause for 3 seconds after a boss to take a drink of water, by the time I put the bottle back down the DPS has run off

I am not talking about the case where the tank only pulls one or two packs and the healer is encouraging to pull more by bringing a few friends. This isn't a small packs vs wall to wall issue.

I don't remember really ever seeing this on NA/JP DCs but maybe that's changed too?
Is this something players on other DCs are seeing?
