This a great game, but it could be better. 

What I miss for my perfect Fallen Enchantress game:

- AI BRUTE FORCE challenge. LH messed up that big time, however indirectly with the champion/sovereign buff. Give me harder AI troops to fight! More depth to Spell resists and Elemental resists would be great. You did a great job with the sovereign/champion system, but that nerfed the AI sadly. They still do not know how to use champions in combat. So buff those AI troops. You had a good idea with the AI only abilities, but they are way too weak at higher levels. Do not be afraid to punish us Ridicilous+ players (Hit us with 10+ tactical regen, we can handle it ^^ )

- Implement the mods, pay them or whatever, the mods are improving this game more than your DLC's, you should implement them into the main game when they are good enough. Don't just add xml code. More graphics, more spells etc. Use the mods to improve the game, and build from them where the work is. (art etc. especially) Point is, use the modders to improve the game not the other way around, I am sure they will be happy if you use their code. 

- Monsters and lairs need more depths, it worked better in FE imo, in LH not so much anymore. Longer quests that you can start with at start, would be awesome. Weak/Medium/Strong/Epic needs more differentiation. Epic is not epic when your army is epic.
