edit: obviously not like I have actual experience with high leveled play, just my opinion and analysis.
6 item cait is not a stronger carry than 6 item vayne. Vayne has 3 built in steroids (q,w,r) and deals a ton more damage lategame than cait who only has one (her passive). Also, vayne can be safe if you use her skills intelligently. She has a stealth, mini dash, and knockback/stun as well as cleanse most of the time.
Less of a hard carry more of simply being stronger. The extra 100 range is intensly powerful in ultralategame where if your ADC dies you pretty much lose the teamfight right then and there.
Plus, much better at poking tower.
Obviously, depends on what you value and on their teamcomp versus yours, vayne obviously has a lot more raw damage, but lategame I see safe poking ability, especially of towers, and extra range if you have an escape, as more valuable then raw dps when you're both dealing ADC level damage. I don't think a low CD dash that's short really replaces that range cause when you're 550 you're still in range of a lot of targeted cc and have very little time to react to skillshots even when that's an effective 100 extra range versus targeted.
espy why dont you main rengar
Also, Saint's SUCH a ****ing genius.
"I'VE GOT IT! We'll replace Westrice with Voyboy... THEN HAVE HIM PLAY AKALI!!!"
Yep. Fool ****ing proof. Genius. Maybe that's why he misses every damn ward on earth.
Lol, those wards, so funny. Somebody needs to tell him to attack move when he has oracles.
Dunno what was up with that though frankly they played really well against m5 in general.
Trist is probably the best late game carry though. Almost entirely because of her range, but the two escapes and steroid help (Put her above Kog and Cait respectively). I don't think her mid game is that much of a hinder. You may want to try and cheese some level 2 or 6 kills in lane though.
I agree that tris is the strongest lategame carry, it's not just her range, safetly, jump (which resets with kills) plus aoe knockback, she also has a really powerful AS steriod which endgame is a lot more powerful then a simple AD steriod because it's multiplicative.
At the same time, no in my opinion, in spite of being the strongest lategame carry she's the weakest adc overall. Even if she wins lane decisively her damage midgame damage is gonna be weaker then the enemy adc even if she's like a BF sword ahead because none of her spells scale with AD and she doesn't have an AD steriod, AS doesn't matter without anything to multiply. Edit: And the mediocore damage she midgame is significantly dependent on her jumping into melee range.
Why is this so important? Cause midgame has the most massive swings, losing early game is significant but can be recovered from if at least one lane won. When you're dealing with midgame you have your first actual teamfights which mean you're dealing with potential swings of 5 deaths, plus drag, plus a tower or two from every teamfight. If you lose early game you can come back, if you lose midgame you're pretty much always boned unless you have superwaveclearing (cough, anivia) and a hypercarry. And you're really good at passive play.
Though in solo queue super throws always happen, still there's a reason why tris has the worst adc winrate at all elo ranges.
