So, just playing the game on my own, I find that you can switch between Miner and Botanist without any real penalty. Combined with the fact that theres some benefit to cross-classing their skills (wards, primarily), I'm wondering if there's a reason to not try to level these two classes together?

I know some areas are very rocky and some are very wooden, but is it really that hard to move between the two as you level up to keep the classes close enough together? I guess if you were rushing for 50, it's not a good idea, but what about getting high enough to earn the wards?

Just curious as to whether most people do both, just one, or both until they reach a certain skill they can cross class?
