I think at this point it's an accepted fact that they are the most asked for race. From how many threads pop up about them on message broads to the poll where they beat out every other choice given. That's all the reason I think is needed really ... provided SE decides to make another race. Heck, you even have the dev telling a fan that they shouldn't give up hope for them and that their high heel is tricky ... leading many to believe it's a matter of when, not if.
Sure, this thread has a fair amount of bickering with those that don't want them but that doesn't discount the post talking about ways they would like to see them or how they can fill in gaps in the current options.
Personally I feel that that can fill the gap for a tall amazon females. FemRoes are more like tall, athletic, goofy women. Like, their emotes and poses don't scream amazon and their body shape is more "I'm a physical trainer and health nut". Sure, you have the imposing stance with fist on hips ... but you also have laid back and cute poses as well as out right goofy school girl stuff like the happy emote.
As for the feet, I think there can be a system set up for it. Female shoes with a high heel and hightop boots can be exaggerated to fit their feet. Flats and sneakers can be turned into a footwrap based on the shoe. Sandals could get string/ lace like treatment and full on heavy armor boots can be plating on the top of the foot with straps or wraps used to hold it on the foot. Bam, makes sense to me.
I mean, that's pretty much how GW2 deal with it with the Charr IIRC. Some shoes are exaggerated to fit their feet with room for their toes cut out, some become foot warps and some become metal platting on the top of their feet. And if you're worried about them putting effort into something only to have it not pay off then I'd say it can be an investment for more new races or hybrid race/ tribe with a high heel in the future.
