"Swift completion" is relative to the game, not the community

[DeaconMoore]

DINGDINGDING We have a winner! I should have included this in the OP, but yes, so very much this!

I do not play with strangers to be challenged. I establish for myself a set of parameters that pretty much guarantees success and renders the experience "idiot proof" (not to call y'all idiots, it's an established turn of phrase) in case of new players or those less comfortable with the pressure role of healing. I err on the side of "take'er easy," because I know that will end in success, and because, to be quite frank, every healer-player I've ever known personally has greatly appreciated and trusted in my care for their stress levels.

And, once again... I am still getting "swift completion" credit and therefore objectively going "fast enough."

OR you could just ask a simple 2 word question "Pull big?" And see what others want to do. You are one of four, not THE one.

Not that you should really need to ask, as such an experienced and competent tank, simply pulling the first two packs and seeing how well the group performs should tell you all you need to know about the pace you can keep.
