Side note about the DW helm. It's most efficient to sit for a med tick, then immediately stand and cast the helm, then immediately sit back down when it casts and wait for the next med tick then repeat. Since the cast time is 10 seconds, you can sneak it in between a first and third tick and only miss one med tick in between (since ticks are six seconds apart). A little math behind this at level 57 where medding grants 19 mana per tick and the helm heals for 122 health per click:
Spam casting the helm and ignoring med ticks gives you six helm clicks per minute for a total of 122x6=732 health. This is at the cost of 10 med ticks or 19x10=190 mana. The health to mana ratio is 3.85. Not too shabby and way better than any of your healing spells.
But...
Sitting between casts allows you five helm clicks per minute for 122x5=610 health. However, you only lose 5 med ticks during that time or 5x19=95 mana. The health to mana ratio while doing this "helm dance" is 6.42. This is way better than the lazy method!
So put on your dancing shoes and get your sit/stand hotkey next to your helm hotkey. No one likes a lazy paladin!
