yeah but partiendo of that point, conquistadores are OP too, in my opinion almost as much as Mayan archer... But I get your pointI agree with the deers placement change, but the maps balance not sure (dunno how much it is balanced). I always being good at adapting at very bad maps so i would kind of miss it :P.
About the Plumed thing i was pointing at you River, Plumed archer is the most OP 1vs1 unit so any guy that played aoc in the last 3 years should know mayans need a nerf.
