Garen - just do w.e nerf you can do, make him weak
Mord - same as garen
Alistar - lower his ult's damage reduction
Poppy - let towers hit her at 50% damage when she use her ult
Anivia
Blitz - higher CD and no stun after grab
Gankplank - do the same thing you did to pantheon before, nerf the **** out of him.
Malzahar - his ult, lower the time for suppress
Kayle - lower her slow and righteous fury
Udyr - same as garen, mord and GP
Veigar - his stun
Vladimir - ranged fighter??? wtf???
Karthus - range of ult like TF and Panth
Lux - of all lux's moves goes too far, and too low of a charge time for ult compare to cait's
Zilean - play against him and you'll know.

here's a better idea, ban you from the game

So nerf all the champs that you don't know how to play against? Okay. Makes sense.

Just L2 not be bad and many of those champions aren't too scary.

facts:
poppy - tower deals 100% damage even during ult
blitz - it does not stun, its a grab that can sync powerfist before the grab finishes.
Malzahar - cleanse makes him useless.
vladmir - hes a god dam mage. his heal was lowered to 20% of damage dealt.
karthus - theres a ****ing ton of items that can make him useless, getting 300MR makes him useless even if karthus gets a voidstaff. they nerfed global teleportation NOT global damage.
lux - her ranges are limited, all of them are skill shots, learn how to dodge.
Zilean - only ONE damaging spell.

you - quit making duplicate threads, learn how to use the search tool.

Nah, let's just nerf Caitlyn, because she so deserves it.

the only one on the list i dont think you are just being a poor sport about losing to is mord because he is nuts but i nerf im not so sure he needs

Guess what? Garen just got buffed!

Karthus is fine as he is. His Ult is what makes him bad ass. So don't hate and Pantheon's Ult was reduced because they had to buff his other stats, but it doesnt matter because his Ult is useless anyways.
