My hunters have alchemy.
For the WotLK era, the unlimited use healing potion is close to a 40% heal.

They're doing their daily Truegold transmute (experimenting with 25x Truegold a day; mats cost a lot more than Life > Air... see if its more profitable), and of course their Grizzly Hills dailies.
The Priests are mid 77th, having only done 6 minutes of Grizzly Hills dailies, faithfully everyday since level 73.
