I despise how, currently, turns are implemented in combat. Basically each player gets a turn to move all his units, most units having multiple attacks. This is just mundane and archaic.

I would much prefer a turns system similar that of Heroes of Might and Magic V. Instead of each player getting a turn, it is units that have turn. The order and frequency of turns for a unit depends on its initiative stat.

For example, a unit with high initiative would be the first to move in battle and would get more turns than slower units. Conversely, the turn of a unit with low initiative would come up at a lower frequency such that it is possible for that fast units get 2 or 1.5 turns before the slowest unit gets to move.

I think the same system is implemented in King's Bounty.

The way tactical combat is implemented now is like playing chess with each player allowed to move 5 pieces per turn. Not fun and not strategic.
