I think its pretty darn good. The win within X turns is kinda loose...you could make that harder. FYI if you aren't winning...your're not using enough grenades. Also...just plain avoid armor and max out APs.
At the beginning, one you get to 60 ships, ignore the planets, just take citadels and lasers. Use warp gates to take the lasers and citadels if needed.

Sodier: Commander, the enemy are approaching in airships! We have 6 turrets ready to fire on them!
Commander: Only fire from one of them and tell everyone else to cover their ears and yell "lalalalalalalalala" while they get shot at!
Too randomly complicated. Beating level 1 five times is stupid when my level 1 un-upgraded army van beat the 3rd mission easily. All the "combination items" make 0 sense and look to be geared to "premium users" only
Survival mode is pretty easy if you optimize for a long, drawm out battle. Get as much health and power regen on items as possible. I also like the vampire drain on items + aoe skills. Buffs DO NOT EXPIRE, cast them early. Get a ranger and cast the heal over time on all members, it will stay will you the entire 40 waves. Revive (cleric skill) is a must. Most importantly: when there is one enemy remaining - just pass until all of your characters are back to full hp/mp. You should regen about 60 hp and 20 mp per turn just from the ranger skill and item passives. Use benediction to remove curse.
