The following secret was one I learned from Grace Dragonrider.
How I get my potions filled quickly?
Play potion motion up to level 3 then quit for each potion you need filled.
Play one additional time if your mana orb is not currently full.
To get potion motion action started quickly pull the middle two columns down until a few items line up, after that you can quickly drag rows left and right to quickly make matches that will get you very quickly to level 2 if no 3 without any serious thought or effort.
So next time you need to do an instance you can fill up in a couple minutes!
