I checked around to see if there was anything else like this. If so, I am sorry.
I found a way to speed level a caster, using a high level Paladin (I used my 70 Holy Paladin). The paladin follows the lowbie caster, outside of party, buffing the lowbie with wisdom or might. Before the lowbie begins to cast on mobs, the Paladin judges the mobs with Seal of Wisdom, while being careful not to actually attack the mob. The Lowbies casts will proc the seal, and refill their mana bar. Levels 1-10 are nearly a full mana bar every time it procs. And even with the paladin buffs, and seal to fully regen your mana with each cast, You still get full experience from the kill.
On my level 1 druid, I got to Level 10, without ever stopping to regen mana, and never got under 1/2 mana. :wave:
