With the new changes to tank stance, now, every tank can generate constant enmity without an "enmity combo" so ALL tanks are equally viable to pull at the start. Just turn on tank stance and do your regular opener. You'll be the only one doing extreme enmity generation, and with ZERO penalty, you can keep it on, and the other tank will just turn it on to voke and take your place, and you'd turn yours off.
AMAZING.
Rejoice, PALADIN BROTHERS! You too, can be a main tank from the start of a fight!
