1. the hero. can you make him a bit bigger in size so he stands out from his army? He should be a titan in battle with ability to buff up with equipable gear , magic items, etc. be another time consuming aspect we can focus on: beefing up our heroes.
2. customizable city/castle build. as i mentioned in a previous post. building to 1 format kinda steals away the thunder from true strategy.
3. addition of races. maybe a couple more. not too many as too saturate the game but towards the end when most kinks are worked out a release of a couple more would be a cool addition.
4. mixed race alliances capped at 30-40 people per alliance to start. alliance bonuses etc.
5. i dont care much about the economy and balance...as long as we got a strong core here, the game is untouchable.
