the only thing i would say is that the ultimate needs to have some amount of control like if you were placing down symettra’s teleporter or bap’s window. it needs to be cancellable for one, and it also needs to show an outline for where it will strike that can be moved right on top of juno or further up front so you can use it more as a self heal or as a team heal
its a bit difficult to use in its current state until you get a good hang of how it spawns
as for this, i think once you have a solid lock-on it will stick onto the target so if you peek again you can fire it immediately. it resets if you did not fully lock onto the target but you can use it with glide boost to get up close and then back up to fire since distance affects the lock-on time
the glide boost is good but i wish it would reset your double jump ability when you activate it for additional skill expression and movement utility. you can already sorta do this by jumping up to somewhere first and then glide boosting (preserving the double jump for during the ability), but it is a bit clunky and not very useful on areas without much to jump on top of
maybe even allow hyper ring to accelerate projectiles or her orbital ray
