Oh yes, portal to the top of the tower would work too...
Attackable and destroyable towers would actually fit perfect in existing mount mechanics, now that I think about it. A mount already has it's own health and is attackable and if it 'dies' the player just falls off - they could probably just copy-paste that whole bit of code to the tower, it just needs a lot more health.
All that needs tweaking is that, unlike with mounts, players on a tower couldn't move but could still cast. And just think, if they implement that, it'll also be just a small step to finally allowing us to attack from mount-back ;)
