There's unfortunately a lot here that I am in disagreement with, but the apparent notion that there are better champs to carry with than Lucian or Urgot is what bugs me the most.
I'll apply Doj's argument that "everyone is viable" here because there's definitely truth to that. In Lucian's case, he is extremely mobile, almost to the point where some of the Attack range deficit can be forgiven. Urgot is just as capable of massive DPS as the next Marksman, and outranges all of them as well. Of course, Lucian has no CC, while Urgot lacks pushing power and waveclear. These discrepancies are what usually turn people off them, and for those reasons people choose other champs to cater to their strengths, weaknesses, preferences and overall needs of the team.
Other quick notes:
- Neither Ashe nor Sivir are lane bullies when referring to Marksmen; especially not Ashe. Their strengths lie outside of the laning phase. Sure, they can be a pain to deal with in the early game sometimes, but Sivir lacks the range to be a bully, while Ashe lacks the early game damage especially with the removal of her old passive.
- Ezreal's late game is definitely better than MF's, Draven's, or Corki's. I can understand why he'd be seen that way, and it's that he has mixed damage and not much else to bring to the team. If he's itemIzed right he can poke like a monster and/or outDPS a lot of ADC's. Also, he isn't a lane bully either. He's considered to have a strong early game, but this is because of his relative safety.
- I hesitate to call Tristana a hypercarry. After her relaunch she fits in better with the assassin-type group of champs, and is in fact probably the most Assassin-like ADC in the pool. Her mid game is batshit crazy, but her late game leaves something to be desired. She doesn't scale as well as Vayne by any means, and Attack Speed doesn't serve her that well - Explosive Charge, and her kit in general, promotes build Attack Damage-heavy builds, in a similar vein to what Graves and/or Draven would build.
I'd write up a lot more on this, but I ran out of time...
