Take it easy, Tanks.

We also have mitigation to offer the tanks and I think a lot of healers overlook this when it comes to pulling trash mobs. It seems as though there is some kind of ingrained behavior that can be observed with middle of the pack healers where they never use their mitigation during mob pulls. I can only imagine that they equate a long cooldown with the ability being "precious" and are reluctant to use it outside of anything that is not a boss fight. However if you use these abilities at the start of a pull they're usually ready by the time you get to the next set of mobs or boss.

You have a versatile and powerful kit as a healer, you need to use all of it in a smart way instead of spamming a single spell because you found yourself in a situation you failed to prepare for. You should always be prepared and have a plan of how to keep someone alive for situations you have encountered before.

example of me finding myself in a situation where tank immediately pulls everything at the start of a run when playing AST:

Largesse > regen > Earthly star on tank > Collective unconscious on tank > observe tank health for next 15 seconds > respond accordingly with oGCD heal or using stellar detonation

That's not difficult to do and it won't drain your mana at all. because you've provided a secondary regen, damage mitigation and a 720 potency heal for absolutely 0 mana cost... Wow! At this point enough trash should be dead to where your tank is not being bombarded with damage. All 3 healers have their own version of the above, so I don't see why bad Tanks is a good excuse.
