Hi there,
I am playing since 30 years strategy computer games (starting with Apple II+) and wish Stardock the best and hope they could make Elementals a fun and outstandig game.
At the moment, even I have some fun with it, it is only average, but has great potential ... I would have lot of ideas to improve the game, but what to say first ?
So maybe I will start with some improvements I would like and think, which could improve the fun people have with that game, at least I would like it more 
1.) Stacking, never liked it in any game .. so please remove it ... so players and AI has to play more like a frontline game. (Think it is more fun)
2.) For that frontline type of game, give us improvements, which could be built outside (watchtowes, fortyfications, walls and so on ...)
3.) Make it possible that the neighbor hexes could also support attack ... starting from that direction, so a battlemap could consist of 9 areas (3x3)
4.) reduce units on one field and how many should depend how good the leading general is. A maximum of 8 should do it.
1-3 units without hero ... hero charisma 1-10 +1 unit , ch -20 +2 ... ch -50 +5 ... or a new attribut like leadership !
Anything else, how it is now I ALWAYS HATE THAT STUPID , moving around with 12units stacks (Total war and 99,9% of all games) There is no surprise.
ANYWAY 12 is worse at the moment ... battlemap too small and the icons don't fit in a row .. I really hate that ... REDUCE IT AT LEAST to 10
Thank you
5.) PLEASE improve defense for cities, and other things, all that buildings, walls SHOULD BE ON THE BATTLEMAP ! Now it is too easy to destroy cities and defense positions !
6.) Make special Battles for HEROES only ... if I enter a castle I want a castle battlemap and make dungeons possible for Heroes !
7.) Put all writings into the QUEST LOG ... to read it again and don't show the next location on the map ... give hints in the description where it is ... and you have to move with that Hero close to that location that it shows up ...
and a lot more, but that would satisfy me for the start 
ANYWAY WISH YOU THE BEST AND HOPE THAT YOU COULD MAKE AN OUTSTANDIG game out of that , in my own interest 
Best wishes to the whole dev team
Alex
