Will the underdogs come back? Who're you waiting on?

So I am a big fan of underdogs, but it gets really hard to play them when everything they do can either be done better or be outclassed by other champions. For instance: I like the champion , but it seems as if she's too weak to carry and lacks the CC or utility to aid via being the team tank. She seems only good for jungle control or following up on team fights by picking off low health enemies. Wouldn't a little more damage or CC in her kit make her better able to fill one of those rolls? Maybe adding DOT poison to her human Q and spider autos would give her a little bit of an edge or something (not my idea. saw it on a post and thought it was good). Another way to help her keep up with the times might be a little more mobility to help close gaps and catch people more often. So if I had to choose the champ who needs a little push in the right direction to wait on, I'm waiting on the Elise buffs. Anyone else got a favorite who's either weak right now, or just doesn't fit with the meta very well and doesn't see play much? (One of my friends is an main who insists she's coming back any day now and another mains all ADC's but swears 's coming back soon and never fully left.) So who do you guys want to see put back in the meta/top tiers of their respective roles? Any ideas for what they might need to get there? I love to hear what people think about the underdog champs.
