Most people especially on the forums are builder types and dislike/hate warmongering/domination type civs. Most also do not play multiplayer either so singleplayer bias is a tad strong as well. Any civ strong in that regard will get calls for a nerf. I think they should just buff up the other civs to have just as many bonuses as the newer civs instead of nerfing individual civs. To be fair some of the GC criticizers want the general stacking to get nerfed, but nothing else, which isn't a horrible idea, but it is better for the game's design to just level out the others if you are going to power creep multiple other civs (Gaul, Byzantium, etc) like that.
If that is true it makes me wonder why people call for nerfs in the first place. Its not like some highly competitive multiplayer game. The time they spent planning and implementing a nerf they could have been looking back at an older civ and seeing what they could do to make it more fun and interesting.
Unless people are genuinely getting steam rolled by AI Bolivar and want to clip his wings in some way.
