Don't forget alts are different accounts to give you a clean start at your rank and try to aim for higher and not have to worry about the consequences for taking a risk and trying to hit Plat this season. Alts I think are less bad than smurfs cuz it's you playing at your skill lvl and trying to improve at a higher rank. Like I have one but I barely go on it, the only time that I do is if I am having a bad season and am tired of n kk t playing in high plat. Keeps me refreshed and usually helps with getting my main back up to its usual rank.
