When searching under "marksman" in the client store...
There are a few champions that show up who don't seem to fall within "marksman" standards.
While jayce can be debatable, the other two not so much.

"Marksman" doesn't mean "ADC bot lane duo".
It means "ranged auto attacker".
Azir and Jayce are both considered secondary Marksmen. Gnar was originally going to be considered a Marksman, but they ended up changing his typing to Fighter/Tank.
Azir is Mage/Marksman Jayce is Fighter/Marksman
