Where are those cannons??? Ha he didnt build an... Oh there they are.. And so many... How did I miss those?
I still wouldn't use BP. In a game that requires 15k for academy 6 I'm not using BP for anything else.
Right, the 50bp can be rather excessive when you really need it for other upgrades or just go with another resource, ie. requires both gold and grog. I'd also like to propose dropping that to 30bp or so.
