Since we are a couple weeks in and starting to hit the tougher bosses there is something I would like to bring about.  Everybody should start stocking a healthy supply of either;

- Golemblood Potion http://www.wowhead.com/item=58146

- Volcanic Potion http://www.wowhead.com/item=58091

- Potion of Tol'vir http://www.wowhead.com/item=58145

These potions are far above whatever potions of haste provided for dps in wrath.  25 seconds of a major stat, up to 50 seconds when pre-potting, can easily be 3-5% more damage on bosses when all dps are popping them.  Healers can even pre-pot a volcanic potion for extra healing power in the beginning while still being able to mana pot later in the fight.
