>Funny that you should mention it - that's actually what I'd prefer right now

I know, you already mentioned that ;)

I don't like the whole flagpole thing :/
What do you want to solve/achieve with it? The only issue I can agree with in CR was that you could build a tower (only when construction material was deactivated!!!) to get into the enemy base (walk there->activate conkit->build tower->jump into base). But I do not think we could not solve that another way than restricting construction by introducing some magical flagpole-base-radius.

Not talking about the healing here, because that is not necessarily linked to the flagpoles.

I am currently all for letting the player do stuff as freely as possible (sandbox like) and try to build an interesting and fun game experience around that.

PS: Why can the player not build a building at that position? Because it makes sense gameplay-wise? Because it is not appropriate to have that building at that position? No, because someone decided at some point that you should need a magic flagpole to build stuff.
