its not very actually because ling/lanfan is huge among fanartists but not as much among fanfic authors theres some ships that are just like that i guess (and also then theres the whole is it big on tumblr da pixiv etc)

yeah i was like ??? at the ling/lan fan tag bc everyone loves ling/lan fan. i dont look thru the fma tags on pixiv/da/tumblr so i guess it was just easier to look at ao3. i know theres a fair amount of edling on pixiv tho
