SS tier Caitlyn (TOO SAFE) Draven (TOO MUCH DAMAGE)
S Tier Quinn (BLIND OP) Ezreal (STRONG POKE) Graves (A really good balance of damage, defenses, blind, gapcloser/escape/steroid) Varus (sniping, strong burst with good blight management)
A Tier MF (No escape but lots of damage, good at farming, snappy AA, strong hit and runner. Heal debuff good in duels because most ADCs take LS quints early now along with Dblade or Vamp Sceptre) Corki (dem mana costs... but strong burst and escape/engage potential)
B Tier Tristana (All ins like a baus. Gotta learn how to farm with her because her E can mess up last hitting. Initially very weak, cannot duel early. Once you get a couple ad items last hitting under the tower isn't that bad.) Vayne (gets bullied around but if she gets 1 opportunity and she's any good she will kick your ass) Twitch (what I said about Vayne. Vision Wards OP against both though)
C Tier Ashe (she's ****.) Sivir (So is she, even if you're god tier with her shield. If you get a lead you're golden though.) Kog'maw (I've seen Kog'maws do really well in lane. Their opponents usually suck ass, though.)
I think this list is situational and depends a lot on the support though.
