Yeah, I think so.By that i mean creating slighty different bonuses for EW while keeping old for RM and preserving civ identity of course.
Just make Eagles cost 35 food/50 gold base, with Supplies needed to lower their price @20 food a pieceYeah, I think so.
For now, meso civs with all in Eagle seems to be too good. MAA takes up a too much food even if it counters eagles.
