All maps have nearly the same layout. Home island sub mid, mid mid. Some don't have sub mids like garden or TeaParty but otherwise every map has this layout, excluding minions every island that is not home has at least 1 level 1 diamond gen, what if more upcoming maps were different, simple islands with just a lvl 4 iron gen on them. Or a good gold gen? This could add some variety to eggs, instead if you building for diamonds why not make it so you can build for more gold? This may not be very significant but just a thought.
