Thank you for your kind welcome. To answer your questions, I am playing on the easy level, however I am playing on 2x. I don't understand the whole speed thing and I haven't found a good explanation of it either.
In my first tribe I got a Master Farmer but not a Master Builder or Master Scientist. This time I got a few Master Scientists but not the other two. I'm feeling like it's impossible to get all three.
I have read through several study guides and try to blend them. One guide said to have all of the tribe work on research, farming, or building until they master it. So I started off with Master Scientist (gosh that takes a very, very long time to achieve). It now seems to me that they can't be a Master in more than one thing. Another guide said to have 2 people on foraging, 2 on building, 2 on farming until they master it. It also mentioned having 2 healers, but the highest I get with that is Trainee Doctor.

I am open to any and all suggestions :-)

Perplexed,

Matt
