We have only one Pally in our 10m twinkgroup and would like to attempt halfus hc. as we need our hop for stack reset, we have to rely on blink (our mage slacks ) or the potions. so its either free action potion http://www.wowhead.com/item=5634 or living action potion http://www.wowhead.com/item=20008
ild pick living action but most seem to use free action potion.
