Champs that are Broken but not OP
I DO NOT THINK THESE CHAMPS ARE OP.
First let's define Broken and OP.
Broken: Generally lacking counterplay and is unfun to play against. EG.
OP: Outclasses most of it's opponents due to sheer stats alone. EG. 
Now to the list:
: Boing, Boing, Boing.
: Fuck that ult, just... FUCK IT.
: I Q, You QQ.
: The implacable woman.
: Erectin' a Sentry. And Another. And another.
That ult will make you cry at night untill you can get a zhonyas. And god help you if you're not AP.
and
Untargetability and mobility.
Anyone else you think are broken BUT NOT OP.
annoying piece of crap to lane against
.
, the ghost would be doing as much physical damage as an AD support. With 2 of those items, the ghost will be doing as much dmg as yorick without his ghouls. It will also deal damage from Kog's, Vayne's, Varus', Jinx's, Miss Fortune's, Corki's passives.
This only champ i played with that carried a whole team by himself.. not sure if just high skill cap or some broken element to him...
my spear gains power as it flies away
: When a Zed ults me, recalls, then pushes R to come back and laugh as I die there's something wrong.
3.
: Level 6? No QSS? Smiles
: Click RWARWARWARWARWA (On a note, WW's ult is immune to all CC except knock-ups. It will cancel the suppression, but will still do damage as long as the target is within a certain range. PBE post under my name from a while ago about it.)
: 200% AD Ratio on an 80 second CD at level 1. Oh, did I mention it's targeted?
wtf I towerdived at level three and she turned into an egg what
omg total invisibility
the only counterplay is if the player has Pulsefire they probably suck
omg dat burst
omg %hp true damage no counterplay can't build against
wtf ranged and a tank
Hit by her snare, reported for afk.
So sexy her charm always hits you
omg much utility yet very adc

Too much power frontloaded onto pull
I love her, but her ult makes me cry when I'm on the receiving end.
(me): I have sacrificed every 55 mana I used on my maxed E to wittle down enemies. Works like 90% of the time
: What is mana & HP? DEMACIAAAAA!!!! (Fkin annoying silence & spin....)
