The bot lane issue cannot be fixed while the games are this short.
Adcs and supports spike too early now because games last too short, because it was fine for them to spike 30+ minutes in because the games ACTUALLY lasted that long, in fact thats why they had to recieve so many buffs and why adcs were so trash a year ago (you needed 30 minutes to scale when games end in 15).
A lot of the game issues would be fixed with longer games and more stable early-mid-late power curves, and yes that also means making towers exist in the game other than free 600g snowball machines.
Also items like bramble vest need to not exist, seriously, i dont know how this item that is worth about twice its costs in effects got past testing.
