Yeah thats what I do on my MNK too. Also since WHM is the FoTM Healer now, Perfect Balance > Arm of Destroyer on WHM's Green DMG reduction heal area is really good, or slap him with 10s silence when his equanimity is up followed by Feint > Somersault. Most of the people trying to pillar you your Shoulder Tackle will rush but not deal damage and stun and not go on CD. Which is really good, though it is unintended. Personally I'd prefer if Shoulder tackle did 150 potency damage and just a rush attack instead of having a bad stun tagged with it.
You can't face cast a MNK, if he gets his GL3 and does all correct positional attack. My MNK itself did 1k True Strike crits on top of Auto Attacks critting for 400-500 on R30s. BTW... Silence doesn't have DR since When I Perfect Balance I can always silence 5 times with equanimity up.
