Firstly a kick starter campaign would be great for the game and development team to really help get peoples ideas into reality then some of the more unrealistic ideas can become a little more realistic.
more options for micro managing towns/citys
Circle around selected troops showing the attack range
The ability to place your own buildings and walls and have defensive structures would be great (i'm not sure if this would be possible) it would add another layer of strategy to the game and each attack would be different as each players base layout would be a new challenge with each attack.
but the major thing right now for me would be a kickstarter campaign which could potentially bring in a couple of hundred thousand plus more for the dev team.
