While I concede that mist elves are mostly only worth it for the role-playing aspect, I think they're a decent fit for Necromancers. You get Alertness/Alchemy, Herbalism, Dodge, Stealth and Find Weakness, Appraising and Food Preservation, Literacy and Concentration, and let's not forget (white) Necromancy! My current character (lvl 17 - just finished the Pyramid in overtime) has an entourage of well-trained Stone Golems that I often have to station somewhere so they don't destroy everything and steal my exp. Learning and Mana are 32/34. They make fantastic arcane casters. His spells include frost bolt at efficiency 49, and with the fire immunity from crowning I'm rather looking forward to ToEF.
Granted, I had to be super careful at the start. Spawn run to the SMC, then straight to the ID -> lvl 10. By the time he emerged he had no trouble blasting through the VD and PC. Now he's double post-crowned (lust of glory and shirt of the saints) and a rather decent melee fighter too. Hasn't even sat foot in CoC yet. Once I get his elemental intrinsics solid, I think he's good gate-closer material for sure.
