Tristana
People say Tristana is really bad at the moment, I agree, but people are saying riot should give her e bonus damage, give w some me ad scaling, make ult scale with ad, buff as range, etc. I personally think they could give her a few small tweaks that'd make her pretty good and at a better position.
The first Tristana buff should be making her invulnerable while in mid air with w, not saying make her immune to cc but just make it so when chasing you don't get two shot by the enemy adc. The second buff should be making her spells shred armor and magic resist or give the q a percentage of hp damage. The reason I'm asking for this is because riot says "Tristana is bursty" but if you actually think that's one of her good aspects why make it so she doesn't do any burst late game, you know the only time in the game when she is relevant. Riot really needs to give her some kind of buff that will make her Atleast a little relevant, if you look at jinx she is just a better version of Tristana, so what's the point of even picking Tristana? We need to make her more diverse and have something that allows her to have multiple play styles, we need to add a unique mechanic to Tristana or Atleast set her apart from jinx.
