See Sparrows are effectively 3 parts cosmetic and 1 part functional gameplay item. So I don't see a real reason for them to stay on a random roll system. What is the point if even having random rolls for Sparrows in the first place if we can just require them from collections until we get the perks we want. Furthermore Legendary Sparrows and Exotic Sparrows feel virtually indistinguishable. To the point that vast majority of Exotic Sparrows should really just be Legendaries. The only Sparrows that really qualify to be considered true Exotics are AoT and the old Dawning Sparrow that literally leaves trails of Glimmer are you ride around. Am not saying every Exotic Sparrow needs to have unique perks. But if Sparrows are going to be mostly cosmetic anyway than let the players have full control over what their Sparrow Perks are. Bungie already did this with Ghost Shells so I don't see Sparrows as much a stretch.

lol ok

All Sparrows up to the speed of 160, sure but all of them up to the true speed of AOT? Maybe, people tend to forget that while AOT is faster than every exotic Sparrow, it still sacrifices a ton of handling for its insane speed. And while this is an advantage to certain areas, like the fallen mine defusing race in Grasp of Averise, AOT's speed is easily its downfall in another equally famous Sparrow riding encounter, Prophecy's Rainbow Road. This is not to say its impossible to boost all the way down Rainbow Road on an AOT it is much harder on AoT than on other Exotc Sparrows because it goes significantly faster, thus making it harder to make tight turns and recover from mistakes. Likewise there are some players who enjoy the slower Sparrows as they find them easier to stear and control. So if we had to choose one or the other, I think a Sparrow transmog system would be more likely than making all Sparrow as fast as AOT.
