The Monk Temple Reborn

[Reinfeld]

Anybody gotten a good feel going for when to use Meditation in the middle of combat?

Pretty much never as long as you can hit an enemy. 320 potency/5 GCD = 64 potency per GDC (+ you can only cash in on that potency if you manage to reach 5 stacks). It's meant to be used during times where you're running between enemies or you can't hit them for whatever reason. So stack up before a pull, try to add stacks if boss goes invulnerable or enemies are far apart and shoulder tackle is down.
