Personally, I think Aldur's is perfect for a meleementalist
20 Oak Sage
20 Armageddon
20 Volcano
20 Fissure
1 Moulten Boulder
20 Firestorm
1 prereqs for a total of 106 skill points
Fissure should be fully synergized and the fire side of Volcano should be fully synergized as well. For bosses, just stick a volcano under them. For crowds... lay down a fissure, Throw a twister charge in behind it with Geddon running and start swinging. I'd experiment with Amns and Shaels in the jagged star.
Another option is
20 Lycanthropy
1 Hunger & pre reqs
20 Armageddon
20 Volcano
20 Firestorm
19 Moulten Boulder
1 Fissure
The object here is maxing Armageddon damage and using Hunger on a wearbear to keep you alive. If I did my math right with the set damage bonus you get 106 health per bite on a 6 frame attack (assuming 3 shaels in the jagged star) with the Wearbear while your Armageddon does 4648-5491 damage. Armageddon will only last 12 seconds with this build though so you'll have to recast it periodically.
