I settled on these initially and I could probably cut out Barbarian perhaps a few of the casters and just use the spell lists depending on their balance.
Paladin
Barbarian
Archmage
Nightblade
Druid
Warrior Mage
Necromancer
Warlock
Conjuror
Shaman
Looking at things closer I know I definately want Paladin, Warrior Mage, and Nightblade (I like the idea of a magic based assassin). Archmage I'm kinda torn on, I like the idea of the build your own caster from multi realms but I just worry if the increased SLA costs are enough of a balancer for the Archmage.
All the rest of the Companion professions just seemed like variants and real odd ball professions (tarot mage anyone?).
