Was it Riots intention for Marksmen to be mandatory?
Ive played this game for 6 years, and 99 percent of that time ADCs have basically been a win consition.
Ive had games with no tanks where i think "damn, this sucks, but its manageable" . Assassins and mages? You can build a comp without one or the other. Support class? Take Brand, Annie, Zyra, Vel, etc instead. Perfectly acceptable.
But 99 times out of one hundred, not having an ADC is an instant loss. Sure there have been outliers such as Ziggs and Morde, but these outliers were quickly nerfed ans Marksmen became mandatory once again. If i see my bot laner lock in a mage (except for maybe 2) or god forbid a bruiser i kiss my LP goodbye.
Whats up with that?
