Virtually all bot players are also adc mains. Adc mains are not asking for more diversity so they can heimer and swain bot. People that don't even play bot aren't asking for more diversity a the role they don't even play. The only reason for this diversity push is to shake up the pro meta, but it is at the expense of 20% of your player base. Riot just needed to tone down adc late game a bit so other classes can actually impact the game past 30 minutes if they get fed. Not sure why the dumpstered their base stats too.
