Well, depending on how much your village grows, getting L2 in Building isn't necessarily a bad thing. You can get a builder to start a second hut with patience at L1 and 13 villagers, but you can't get the third hut built without L2 in Building. But yeah, I like to get Farming L2 first and out of the way, then test to see how far I can stretch things out in getting the other techs. ^^
