Noble Residence will certainly get my vote - totally agree with Fishslice.
Some of the supplies are disgustingly expensive but I encourage all high level players that are happy with their population to vote for Nobles and give them away to lower levels that need the support. After all they are a bargain.
For a moment I thought that BB are nerfing Mr Myers. Then I realised that they have just adopted a different way of describing it. I think this is confusing for many less adept at maths or in English. BB: you should adopt a consistent approach to describing increased productivity!
Is it really obvious that Mr Myers makes the barracks work faster than Drill Sargeant Skunk?
Currently Mr Myers is (incorrectly) described as "quadruple recruiting time for 1 hour" by which BB actually means that barracks productivity is quadrupled for 1 hour (you make 4x as many recruits in one hour).
