Tides of War, a balance mod

[Gaspar]

After seeing feedback I'm thinking:

America: UB is the Frontier Post, a Grocer replacement with 1 free merchant.
Germany: UU is now the Riesengarde, a Grenadier replacement with 15 strength.
Russia: UB is the Research Institute, now a university replacement with 1 free scientist.

I get why we all felt the way we felt about the Grocer change, but I do think that civs that have "later" UU/UB really need to be very good to get chosen. The problem is you get to a point where you're either nerfing everybody who has Ancient/Classical stuff or your buffing everyone. I mean, these three are clearly the worst because everything was late, but nobody takes Spain either, for example.

Still would like more opinions on CHA and the tech cost change I just proposed.

CHM might just work best with the BTS version but the extra ancient happy moved to a building that 1) is something someone wants to build after the first 50t and 2) isn't provided as a free in every city bonus on a wonder. Maybe Libraries?

The tech cost thing might work but at the same time, I start to worry if this is the point where minimalist balance mod turns into KrillMOD. For me, the largest appeal of this vs. that is that it tweaks as opposed to overhauls.
