Shes in the "gutted" subcategory. Shes not even an ADC anymore until Riot buffs her out of the bin.
I've seen some pretty broken Kalista's in my day
not when I play ADC against her, but still
I like where this is going, but I feel some of these could fit together in one category. For example, "Shredders" and "Tankbusters" are fairly similar (though not completely) and could probably fit into one class. Champions like Sivir and Ashe could fit into a different subclass, focusing more on utility rather than raw damage. Most ADCs are naturally good at kiting, so there's no need for a "Kiter" class.
Well obviously this is up for debate and could use improvement.
This is more like something I thought up if I HAD to make subclasses for them, and they could only choose one. Theres a lot of overlap between subclasses, and some champions can fit into more than one, but I tried to only pick one.
Nooooo, Graves is a caster man
He just throws a Q R for a nice, easy 1000 damage
That and the "Kiter" thing shouldn't exist, since any adc with a dash could be a kiter
