That wouldn't be necessary, since the barely decent change they're going to implement is only giving every sparrow the same speed as "always on time" so as to make all sparrows viable which is kind of neither here nor there. Giving all sparrows that speed plus all intrinsic traits gives you the choice of really using any sparrow you like

Transmog will make aot look better at least

But with the coming change, any sparrow will run as fast as AoT. I don't know if there'd be a reason to keep running AoT after the change kicks in?
