ok so many people have 2 accounts or more some people cheat with them some dont i personally dont

my alt is Ryan2 of course i was wondering if it would be considered ok to play a 2v2 game with my accounts Ryan and Ryan 2 on the same team i wasn't sure if it counted as an "unfair advantage"

Several players do that, it's easier than trying to cooperate with another player who has their own ideas on how things should run, but it's also less fun (imo). There's nothing (morally) wrong with it, though there are other disadvantages.

I did that with two of my older accounts play 2v2's with myself as a teammate. You can make a seamless attack strategy which can take lesser opponents out of the game rather quickly. However, you lose the creativity of two view points and against well communicating teams its not that easy.

It would be morally wrong if you were however playing a FFA or team game and using one account to boost the other.

Fizzer said at one point, that using own alt on a Ladder is not permitted. Even in same team of 2v2 Ladder. However there was a number of teams of player+his alt regardless, and seems like Fizzer did not do anything against them.

^ Don't test this out

Yeah I wouldn't do that on ladder lol. You never know when the hammer will come down.

Well Summer got to number 1 with her alt on the ladder a few days ago, she left now but she suffered no consequences as far as I know

Well it just sort of testing the waters if you have an account you care about it might not be worth the risk. To each their own though I don't think it gives anyone a distinct advantage against elite opponents.
