Good thing I previewed and saved myself from getting Swordsage'd . Looks like two other people have explained mana regen.
@ Jarian: Not nearly as much commentary here (after savaging the Death Knight; it was a labor of love I swear!). This is awesome and I can't wait for Shaman (one of the few classes in WoW that doesn't have an easy 3.5 counterpart). Excellent work .
