What, really?
Ya new level of hogs ?
I would have really liked some hero levels just like the additional walls, to put some DE into upgrades.
I'm ruling against spending hammers and books this time around. I've got 2 camps already updating, and farming for the 2 other ones will generate gold for a couple of towers, then I'll finish up the towers and sink the elixir in walls/research. I'm saving my precious for major stuff, and this ain't it.
