However I still think Varus has more potential compared to Aphelios xD
I'm not sure about Sivir since I didn't play her much, but Miss Fortune should definitely be take to another tier, I rarely get an S with her honestly, but I think she should at least be in the A tier... and SENNA SHOULD BE VANISHED FROM ALL THOSE TIERS !!!!
Vayne may be a bit overestimated in strength. Ashe and Caitlyn are such high priority and tend to keep her in check. I think most A Tier marksmen outperform Vayne, an exception being Twitch but his buffs might even push him ahead.
I agree Miss Fortune is about a B Tier marksmen on 10.17. You might want to keep an eye on her though. Her buffs look very promising.
Otherwise, this is definitely one of the most accurate marksman tier lists on this site. I gave it an up-vote.
Fixed it for you.
Otherwise it's pretty much perfect.. nice job!
