Also, if you put the opposite boosts on the same island (fire/cold, plant/metal, water/lightning, earth/air) they still will not cancel each other out. You may see a positive and negative boost at the same time (for those with opposite elements) but that doesn't mean they cancel out. For most dragon levels (especially the higher levels) the earn rate with positive and negative boost is less than the original base earn rate.
