The only possibility of multi-classing elements would be for example Ral Zar'Rek case. Where Lightning is his base, but fire is his secondary.

Thus people can have multiple's if they follow the rule/catagories above. Meaning someone cannot control water and fire. Though can control Water and Ice.

As for being a Druid style healer. Anyone can have potions, poisons or ointments that were made by herbs. However the purest form of extracting a herbs healing or damaging is by someone with Nature based magic/tech. (So someone who does not use nature and wants to use poison. They would get their poison from a Nature user, unless they want a less potent version of what they seek.)

Sorry for the thorn in the side, but having two elements is something I recently disagreed with. Can't very well go back on my word now. So people should stick to one. (Unless they are sub categories of one another. Like Water & Ice.)
