Solo join TfT ranked

Hello, I am typing this in the board so that maybe something can happen with TfT ranked matches. I am sure we all know that TfT is a very random and getting characters we want is always a hard thing to do. I have found that people are using 3 accounts at one and making a party then joining joining ranked TfT match. When someone uses 3 accounts they use 2 accounts for taking our characters away from us so that the 1 account they care about is lvling rank fast. When someone uses 3 accounts it not only makes it difficult for the rest of the ranked players to compete with someone using 3 accounts by tainting to random pool. Also, when joining as a preset team it is very hard for people who join their TfT match and win... Why you ask ? because they talk on chat and conspire as a team to go against the people who had no choice but to be thrown into their preset team. That isnt fair !!! If it was solo join for ranked then no one can use 3 accounts to cheat and preset teams wont have the advantage over the people stuck with that preset team. I think TfT is amazing but the random part is tainted and spoiled by preset teams and cheats using 3 accounts at once.
