If you play Lake Wololo, you are asking for people to build lots of towers and have cat-and-mouse game. If you don't like the game style that map offers, don't play it. We're not implementing features just because people want all the maps to have the same game style.
With 60 minute peace and normal (blocked) map you can't improvise and adapt much
Why not? After peacetime when I send my first units out I see how many towers the enemy has, if it's a lot I start spamming militia. That's adapting and improvising in every sense of the word. Or maybe if I see my ally has a massive wood economy and I've only got iron, I'll ask him to make 100s of militia for the towers.
I don't really see anything scary or frustrating about towers. Once the 5 rocks are thrown, that's it, you can march straight past them like they aren't there. Militia are very cheap and it only takes 3-4 militia to empty 1 tower (if they're charging so the towers miss a lot)
At the same time, defending your base with towers is a legitimate tactic. It will usually buy you some time because your enemy has to get enough militia to push through them (or shoot them all with archers) but you'll also have a very weak economy compared to the enemy, and so probably very few troops. If that person had build 50 crossbowmen to block his entrances instead of 10 towers, you wouldn't be complaining. I find crossbowmen FAR more scary than a tower, crossbowmen don't run out of rocks.
I don't see how building towers means you won't have an active, fun game. I've had many active fun games with enemies building 10+ towers. If you want to restrict towers, you are just limiting the tactics available to players. Varied tactics should be encouraged, they make the game more interesting.
