Since i started playing on my account that my friend lent me 1 year ago,i realized that i cant play on it forever and i should make my own account.Too much stuff happened on this account and at this rate getting into something higher that silver 2 is a pipe dream because my mmr is so darn low and i cant do squat about it.So how do you lvl up fastest ?
Just do as I say
~~ get a bot to lvl up for you cause you are diamond smurf with no time for that~~
play ARAM and hope to god you don't have any bots on your team. or play TT cause the games are faster.
You'll get more XP per game if you comepletely feed(you probably don't but as a reference) per minute
If you do better in SR (like going 3/0 in lane and getting lots of towers) then your XP gain from there will be slightly higher per minute
so it's a matter of skill+choice
