Suggestion for the Support rename: "Defender"
Alright, I know the support rename isn't all that popular. But if we are gonna rename it, how about instead of going with a weird name like "flex", we take a page out of football and call it "defender"?
After all, the only things all supports have in common are An imperative to set up a line of wards- basically locations that are easy to defend due to having vision-, protect the Botlane from ganks during lane please, and (arguably) keep the back line untouched in teamfights.
It's also less demeaning than "support", and it's easier to remember because it's already used elsewhere.
While it's no argument that some supports "defend" more than others, they all still have to work with the AD during lane and they all still build sightstone (unless they are just trying to become a second midlaner, in which case I wouldn't call them supports either).
So... Defenders? "In the botlane, it's Botlaner Stixxay and Aphro on Defense"
Kinda like it.
