Learning stuctures.

[Spuddicus]

A quick cross-thread note here - In the "Ranked admirals" thread, it was pointed out that learning buildings probably give admirals retinue (and thus stars). So there's a reason to possibly build learning buildings elsewhere besides the capitol, since your fleet might be god knows where.

I've noticed this in my current campaign.
Filthy rich and going slow growth on pop so I've been building them when there's nothing much else to build. With Scrips I've been getting a bit more (well, more than none) one and two star admirals.
