I really like the idea (and think it makes more sense) that the shaman is more an elementalist than a nature mage.
It should have training in two non-opposite Elemental schools, chosen by the player (this is mostly for flavor), and in Nature level 1 spells (except for
spirits, which would bring a really cool addition to the game, as well as allowing spectral/ghost oriented necromancers or even a Bog Prince Lich Mage - obviously an alternative necromancers)!
Also I'd like very much too see a Kobold Sorcerer trained in Arcane and War schools, oriented in dragon creatures (arcane or maybe war for the more brute or feral types of draconic creatures) and traps, utility gadgets (mostly War 'enchantments' which explode/brake/spend after use). I have more ideas to get more in depth regarding draconic stuff, but it's not my intent at this time in this thread. Tell me what you think!
