Oh, unit design have the same quirks as Elemental. Ok, another two old complains and one new:

There is one problem with unit design: I cannot to design unit with weapon. It means, in particular, that I cannot design my own pioneers! 

Oh, now I can give them wooden staffs for nothing. Cool! But that arises second question: why I have default pioneers at all, if I can upgrade it for free, simply visiting design screen?

 And second problem is unit weapon. I see the same old Queens Staff. That is exact copy of Wooden Staff of my pioneers, except cool graphic and name. Why? Why I am, playing as queen, have the weapon with exactly the same characteristics as simple weapon that can be taken for nothing?
