Welp, I did take a look. probably gonna talk more about a melee balance and what you must do.
must:
1. never use a random level drop of item like permanent 3-6 random drop in the same list or even charge-permanent else you know what you are doing.
2. doodads gap and trees.
3. camp aggro
other:
4. terrain path broken. between red base and lab click 'P' and you will see that there is a path you can't walk on. +cliff broken
5. trees starve [under 180]
6. units camp status. some are blue and some are normal...what? Expo should set as 600 and other should be 200 unless you know what you are doing like i say before.
7. blight terrain...
8. narrow path every where.
addition:
8. why use all mech units at lab camp? first problem is that these guy never drop the corpse disadvantage for UD, also no range or medium armor creep? maybe that was my taste but hmm...
9. every dragon roost have a different. If I remember it right bronze dragon and black dragon do more dmg to the air unit than other dragon. fire and green have strong dmg. blue had slow. and there are something to do about splash dmg which I'm not sure. Go check Knecht wiki book. In short, very unbalance dragon roost choice[to who ever the closet].
10. why shipyard when lab is easier and safer to get? weird.
11. critter choice...
I guess that's not too many
