So the +1 science to specialists is an aesthetics policy now? The AI already spams that policy tree and avoiding it often results in cultural problems in the late game, plus you insanely buffed it already with extra tourism and revealing hidden artifacts. I fear that now aesthetics will basically become a mandatory policy tree. It was already difficult and painful to avoid, now it's just going to make sense to adopt its policies in virtually every game. I very much preferred your proposed balance solution of giving the commerce policy finisher +1 science per trading post, and possibly even giving +1 gold per specialist. I modded that in myself and kept the +1 science per specialist in Rationalism, then increased tech costs in the renaissance and afterwards to compensate. Aesthetics is already very, very good, absolutely mandatory for a cultural victory and if you don't adopt it you might have trouble adopting the ideology you want.
