Buff exhaust or try to change my mind
In my Opinion botlane is the most punishing and less forgiving lane that exists on Summoners rift. Very often people call out for "better bot wins". This isn't just because the adc feels like the strongest class off all, i don't even think that it is in a even game. But almost every single time, your botlane crushes or gets crushed, the reason for this is the exhaust change, that forced a 99% pick ignite meta as support always.
Since supports pick up ignite, kills fall left and right down there. It's so hard for the loosing botlane to not get crushed after a Single mistake that allowed the enemy adc to get a level on. Even in midlane you have tools to avoid getting killfarmed by your enemy, and even toplane doesn't hardstomp this hard so often. If a botlane also get's stomped you are almost always guaranteed to loose the Drakes, and rift herald afterwards if their jungler is somewhat decent, which means the entire game turns into a one sided fiesta, and it feels very bad for jgl mid and toplaners and even loosing botlanes to play a game like this out.
And i don't want to say "well botlane decides the game always" ofcourse that is not true. If your mid feeds than it might just almost feel as bad for a winning botlane. But the thing that i'm seeing over and over again, still stands, and what i'm seeing is, consistent one sided botlane matches, for whatever reason. Buffing exhaust so that it is the to go summoner spell for at least supports like "sona, janna, lulu" shouldn't be to much to ask for. Not to mention that adc's would also feel better if they have some sort of counterplay against a fed enemy assassin, which exhaust should provide. Yet riot for some reason accepts the current one sided clownfiesta meta. Right now you have to grind harder than ever to actually get to your correct Elo, if you are a consistent but not hyper aggressive Player, which is very annoying.
