Req instead of "you" being bugged about which is the best solution for the tower problem.

I have a kind of solution... though it would be "worse" for u problably.

What about, one "choosing" how to build his castle?

Has an example... u still have a limited area corresponding to your castle (has when one takes an abandoned one), u just are "allowed" some X walls + 2 barracks + 4 towers, to put where u prefer inside that area.

This would allow every player to "decide" how to get them, and no one could say that it didn't like where they were put... since it would be it's own decision.

+ would bring the game, an added sense. We would "see" how military architecture would evolve (being that one could have different numbers of available walls, towers, gates, etc in each game type for example... or something)
