This champ is garbage or am I?

Negative damage, outperformed by worse players on easier champions.. why play Rengar and activate 500 brain cells when you can play Nocturne and have negative IQ and do the same.

Can't even kill mages anymore because they have more HP than Sion from items. Can't kill ADC because half of them are now designed as unkillable duelists. Can't kill tanks because they're tanks. Can't kill bruisers because they're too tanky.

Is this just me?
