I've got all the GB I need for now and the ones I don't are way above my era. So palm trees it is :p
Few weeks ago I finished lv 11 on hagia and couldn't go to lv 12 because I lacked blueprints. Just 2 days ago I finally unlocked it.
Don't take blueprints for granted. They are much more needed than imagined.
Edit: Unless if you plan to stop on lv 10.
