Not meant to disespect, just point out its not limited to a 1 off. They have been adressing several dynamics of demeter since they released her. buffing pan and adding hera at the same time, Improving hestia god power and adressing midas. Fixing unit bugs and adding new ones.
Specially since lowering the number on the pop value isnt the most taxing dynamic.
Dunno how it goes in other age games. Here in aom they dont really struggle to nerf units. They have nerfed icarus last patch
