And no one else buys a Pink Ward that Game... Or any other game...
Is a pink ward too 
= usually can't carry against anyone smart unless the person is good enough to carry with some other champion
= its probably not the fact that they're stealth and the fact they are jerkass assassins with jumps
= not a real stealth champion but people have no skills at dealing with them even without them using stealth
