Franks nerf when?

According to aoestats Franks are the top tier(~55% winrate) and most picked(~8%) civilization right now. It's not just this.

In Win Rate by Map section, as you can see they have more than 50% winrate for land& hybrid maps. They only struggle in water maps which isn't a surprise for a civ lack of water bonus.

And according to Lowest Win Rate section , They have higher win rate against 30/34 civs , only beaten by Indians, Teutons, Celts and Incas. Their 5th best counter civ(Burmese) have 49,15% winrate against them if I'm not mistaken which is insane imo. I couldn't find any other civ with numbers like these.

I think these stats should be enough for nerfing Franks. What are you guys thinking?
