Riot, do you have any plans to address marksman bullying creep in S5?
Ever since Graves, every AD carry has been a harder lane bully upon release then the one before them. If you count Vayne as a lane bully (she might have been when she released, I wasn't around for that one), then it goes all the way back to Caitlyn.
For those of you who don't have the list, I'll post it up here:

were part of the original 40. Sivir and Twitch both got reworks later on.
In 2010, we got
in order. Remember that Urgot was an incredibly strong lane bully before he was gutted (in fact, he was usually picked to shut down the enemy AD).
In 2011,
were released. Graves was especially noteworthy for routinely going mid lane and absolutely crushing people. These are ADCs we're talking about.
In 2012,
came out, Varus with powerful early harassment and Draven with an amazing all in with his old passive bleed.
In 2013, we got
, all of whom had EXTREMELY strong laning phases on release. Quinn still sees time as a niche TOP LANER, Lucian is probably the hardest lane bully in the game at the moment, and Jinx is Jinx.
How do you intend to balance the inherently strong late game of ADCs when you just keep releasing AD carries who are stronger and stronger early? AD carries used to be weak enough that they needed supports to keep them alive against the "whatever champions we want on our team but who don't do well in solo lanes" bot lanes in Season 1. Now, AD carries are so strong that most supports picked are only there to secure the ADC more kills. The focus has gone from "if we get this guy to late game, we win" to "screw it let's just kill them a thousand times".
This really shows best when you compare the support roster in S1 Worlds and today. In Season 1, the most played supports were
(though Zilean was played more as a mid laner back then).
These are all supports that are focused on protecting the AD carry and helping them farm and trade. Then the nerf train steamrolled whichever support was most popular each patch for the next 2 years, and now we have
with a little
thrown in. All of these supports except Janna are focused on catching and killing the enemy AD; Janna only survives because of Zed/Yasuo/Fizz mid lane. Why not just take a tank or mage when your AD carry has the burst damage of a mid laner early game?
AD carries have been the problem for a long, long time. The AD carries who are strong early need to really be SIGNIFICANTLY weaker then the other AD carries late, especially if they have mobility. I mean, Kog'Maw may have the highest theoretical DPS in the game from ridiculous range, but nobody gives a shit when you've got Lucian who bursts enemy squishies 100-0 and can actually win lane (and usually does) or Caitlyn who just sits there going pew pew pew from outside your range while still having an escape.
Nobody with the late game DPS of an ADC should be a lane bully at the same time.
