I've had the "is LH a military driven game" conversation before in another recent thread.
While I agree that a military presence is required for every victory condition to be met (yes even the master quest needs some military), the miltary victory condition requires elements to varying degrees of teching, questing, and diplomacy to be successful as well. Thus, I do not attribute LH to being solely a war game. It requires mulitple facets.
I'd love to see a new victory condition introduced into the game, Cleasing the Land, whereby it is up to the player to clear the world of Elemental of all Wildlands. Naturally, for this to work the master quest would need to have it's wildland aspect removed or slightly redesigned so that it is not a wildland. This victory condition would be another that is not entirely dependant on warefare.
That said, I'd also really appriciate if you disable the Master Quest victory condiction, the Pit of Despair does not spawn onto the map. It wastes precious space.
Very interesting post. Comments below:
- Item courier: one of your heroes has an item that your other hero needs? Just click on it and send it to the other hero through a courier that takes X amount of days based on how far away you are.
Agree. But I'd go one step further. If I had to do it over again, I would had a global inventory with the concept of soul binding.
- Independent Cities: much like Civ V, it would be great to see independent cities and have each of them provide unique items or weapons or other commodities.
Ironically, War of Magic did have minor civilizations. But I totally agree that there should be independents that you should be trying to woo to your side.
- A plethora of mounts: I've already found over half a dozen different mounts, each with its unique look, feel and bonuses. I think LH only has, maybe, 4 different types? I want more. They add to the customization and personalization of our heroes.
Agree.
For me, and I'm obviously biased, I really really REALLY don't like lengthy tactical battles. Whereas, I think most gamers prefer in depth tactical battles. If a tactical battle takes more than a couple minutes, I'm unhappy.
About Soul Binding: I woudn't appreciate a soul binding mechanic at all. Having the ability to swap equipment to meet your empire's demands is, imo, paramount. Having a method of transporting equipment over distances should be possible though.
Suggestion: Is it possible to have a 10th unit automatically embedded into each city that is founded? The trick is that this unit would be the SAME unit in each city, effectively making the unit seem to exist in multiple locations. Any ability to move....and perhaps even attach it to a special building that you can construct in your cities, and voila: city to city transport of any item. The obvious prereq: Your heroes need to stop by your empire's closest city to drop off or pick up an item.....imo, way better than having to go the full distance and meet the other hero in the field. Thoughts?
About Independant Cities: Isn't there some way these can be coded into the existing game? Independant cities exist in the scenario. Could they not exist in the sandbox mode as well? Remove there ability to construct pioneers and give them some base amount of metal and crystal and gold to play with.
About mounts: Would love to see several more mounts to mount. Pretty please. 
About tactical battles: Imo, you've really done an excellent job with the current length of the tactical battles. They are long enough to make you really need to think about how to defeat your enemy, yet short enough such that once you've done your thinking the enemy can be quickly dispatched. I'd love it if it wasn't so easy to kite melee opponenets....I've dispatched a juggernaut with an lone archer before. Siege warefare and Dynamic terrain is wishful thinking...
Lastly, thanks for your continued attention on LH. It really is shaping up to be a fabulous game.
ps. I'm probably in the minority, but I think going back to single tile cities in E15 is a step backwards. I love being able to design and develop my multi-tile cities in LH. So, that said, PLEASE allow us to rotate our buildings again in the 1.6 update.
