-what sort of structures can be built? is land control simply going to be a couple towers located in a certian area? or can walls be built, buildings, etc.

-will there be territorial advantages towers? can we choose to put them near populated areas so we can control them?

I'd just like to know some more specifics. Is the boosterpack simply going to allow guilds to build a tower to defend from rival guilds?

Or will there be strong enough reasons to control certian areas with towers, and strong enough reasons to band together to destroy towers?

By the way it's sounding, it seems a lot of people don't like the latter idea as it interferes with PvMers.
And they just want towers to be there for guilds to almost duel over.

And while that sounds good at first, in practice it doesn't last.
DAOC is proof of that. Guilds can hold keeps in the frontier which give bonuses, even capture relics and store them in the keeps, and after two months half the guilds on Andred grew bored of fighting over pointless keeps.
