nope, nope, nope, nope, nope, nope

In order:
Cait's not OP. Nuff' said on her.
Fidles: Amazing mid game, not so great early/late (at all), which pretty much makes the fact that he's amazing mid game worth nothing.
Annie: Not OP, just a HUGE amount of burst. In order to be fully effective, she has to be pretty close to the enemy too.
Vlad: He's been nerf'd to hell and gone, yet he's still amazingly viable. There's not much more they can do to nerf him, asides adjust his passives scaling a little more so he gains less HP from his AP.
Anivia: I... don't see how she's OP in the slightest.
Morde: I have no argument against him.. Because i've never seen how he's OP. He's pretty easy to kill Early & Late game, as hi shield is easy to get past at lvl 1-5 and easy to over-come lvl's 12+

Ahahahahahahahaha, what? You're serious?

Learn to counter champs. Instead of being all "herp derp, glass cannon is the only way to win", you could try building defensively.

Caitlyn giving you grief? Buy a fricking Thornmail. She'll evenutally learn to stop shooting you.

Fiddles? Poke and retreat. Don't let him Drain you by running out of range.

Annie? Banshee's Veil will ruin her stun combo, like it does for any burst mage.

Vlad? Ignite or Executioner's Calling. He can't heal, he can't do ****.

Anivia? LEARN HER RANGE. AVOID HER STUN. IT'S EASY UNLESS YOU'RE BRAINDEAD. Also, don't stand in her Blizzard. It does damage -_-

Morde? Get him away from creeps, and he has no shield.

Jesus christ people, learn to ****ing play the game instead of *****ing that every champ is OP -_-

i just played against a cait with no magic res runes no magic res or health items, and took a **** ton of dmg.. explain that to me, fiddle is the most op toon by far, his fear is nuts idk how its allowed, and he drains life, and he silences, then he has one of the highest dmging ults in the game. annie has been buffed idk how u can say she is not op. vlad can not take dmg, life steal, and has a great ult. anivia doesnt die when u kill her, she has BY FAR the most op passive in the game, at least karthus and kog dies after theres. mords skills are not only amazing, with one of the best ults, but they also allow him to have a HUGE shield.. i play non op champs like cass and zilean.. you need skill to use what makes them good.. i guess my real arguement here is that you shouldnt just give people amazing abilities with no skill required, make people actually try....

with anivia, im not complaining about her skills, they are op when used correctly but that makes her hard to use, that is a great trade off.. what im complaining about is her passive.. it just disallows certain people to even kill her, it is by far way too op

cassiopeia is not op.. no one ever uses her because she is one of the hardest people to use.. people always fail at her.. zilean has only one attack all of his other things are hard to use correctly, and they are both squishy

I agree with fiddles!

Funny how you listed almost nothing but mages.
