Riot Games explains the bot lane meta in League of Legends in the latest Ask Riot. 

Rioter Maple Nectar and Ghostcrawler led the question and answer segment.

"We’ve been mostly happy with the amount of diversity we’ve been seeing bot lane since patch 8.11 dropped. Seeing mages, bruisers, divers, etc. being played in the carry role is exciting given how solved the bot lane meta has been for… well… years. One of the things that gives League longevity is how no two games feel the same and the challenges you face keep you on a constant path to mastery. The dynamics of a lane like Heimerdinger + Fiddlesticks are so fundamentally different than what we’ve seen bot for the past while, and we’re excited to see other interesting strategies/combos evolve over time as the meta unfolds."

The community actually asked if Riot Games was considering a Battle Royale mode. They gave a pretty interesting answer. 

"I think to make a game in 2018, you are supposed to have some kind of Battle Royale mode.

Seriously, though, we had a really hard time even getting Hexakill to work. I’m not sure if we could get 100 or more champions in the game without a ton of engineering effort. We’d want to be pretty confident that level of investment would lead to something really fun."

"On the other hand, there are some really cool things that Battle Royale does that we’d love to be able to bring to League. For example, the expectation that you probably won’t win—you’ll probably lose—is a really nice element. In League, statistically if matchmaking is working really well, you’re going to lose about half of your games. We’d love if there was a game mode where you’re there to kind of do crazy things and see how far you can get, versus just crush the enemy team, but whatever form that takes probably can’t be a Battle Royale."
