What would you (the community) think if Tristana's Ultimate "Buster Shot" was a Skillshot?

I've been thinking for awhile now...I enjoy playing Tristana and in fact Main her, and it's not hard to notice for me that Tristana's Ultimate is really lackluster in terms of its utility and usage. I generally end up dying when being chased by my opponents because when I try to R them, I either end up going back because its targets are too far away or I have to pause a little bit and slow myself down (leading into me being cornered easier). So I've been thinking, like above...what if her Ultimate was a Skillshot instead of a Targeted Ability? Not only would it make her more enjoyable to play because of the increased skill needed...and also the passive utility and potential usage of a Skillshot-Buster Shot...but it would also make her less of a Snowbally champion there'd be actual skill needed in using it. It would also indeed make her more usable in Teamfights, and it would let her be able to damage invisible enemies that couldn't be targeted (Twitch and Teemo being the most likely to show up). On that last point, I think us Tristana mains can agree that Teemo ADC is just so incredibly hard to play against...any other ADC, Teemo included, agrees. What I'm thinking is perhaps taking advantage her Draw a Bead more. Why not have it be a Graves-like Skillshot with the same general attributes of her current Ult, while also passively gaining more range from her Passive? I want to see what you all have to say about it. Please remember to make all comments constructive and non-Flaming to both myself and your fellow commenters. If you'd like, we can also discuss item and spell usage, and her potential combinations with other Champs that would appreciate Tristana having a Skillshot. Have fun commenting, minna~
