Tanking 101

[Bun_Vivant]

If you only ever do w2w pulls when your healer is "confident" then that healer will never be, because they'll never have to get out of their comfort zone and never realize that it's actually not hard to heal.

I've had plenty of healers respond that big pulls were OK when I was tanking, and
I've responded OK to plenty of tanks asking about big pulls when I was healing.
So your use of "never" is hyperbole.
