Being good should be tough, but it should also be rewarding. It's easy to be evil, but that comes at a high cost (even if the evil person doesn't realize it).
This is how most folks seem to describe alignment in GC2. For me, it has too much cultural baggage. I'd prefer to see alignment as a single scale, with a central range that is neutral. The effects of alignment choices would move you along this one scale, and the results would be determined by your distance from 0. Being very close to 0 would generate one set of costs and benefits, being clearly negative a different set, and being clearly good yet another.
And none of the differences should be about "easy vs. hard." It's easy to be good when you live in the Shire. It's hard to be good when you live in Mordor. And Gandalf spent the vast majority of his very long life as "the Grey."
Which brings up the even more fun question--will alignment (good-neutral-evil, not shard stuff) change be possible? If there's a substantial diplomacy layer to Elemental, it could be really interesting to consider shifting your alignment as part of courting an ally, or even better, working magic to shift the alignment of weaker channeler as part of your brilliant long-term strategy. Shifting your own alignment should have consequences along the lines of D&D level loss, maybe a manna drop from which you can slowly recover?
