Tristana?
I've made posts and other people have made posts and it still stands that she needs something to help her out. I figure the only way I'm going to get anywhere with getting her looked at is if I keep making posts on the forum. Here are the links to mine and other people talking about Tristana and her pro's and con's and problems:

I don't necessarily agree with what everyone has said in these threads but I appreciate the fact that they prove there are people interested in seeing work done with her. I personally feel like she has a good niche as the games safest, self peeling late game hypercarry and that's what she should continue to be as. I'd like to see her earn either some buffs or minor changes that better enhance and encourage this style of game play for her. And if not buffs or changes to her, some changes to the meta that just doesn't favor her. :/ As it stands, she gets dumpstered by both Lucian and Draven, who are over bearing and strong. Lucian is a far worse generalist than Tristana ever has been as there isn't really a support or composition that he doesn't fit well into. Tristana at least needs to have some peel and a frontline to carry and do well and does poorly against early to mid game teams. Not Lucian. Lucian is the worst case of a generalist I've ever seen and there's been no effort to fix him, unlike when Maokai was considered a "generalist." Then there's also the matter of Twitch who just out scales her and really all other AD's too; he's been a consistent problem since the start of the season with no work or nerfs heading his way and no appearing nerfs heading his way either.
So yeah, I don't even care if you buff or change her at this point; just make it so she isn't always garuanteed to go against one of her hardest counters every game.
