Team Builder Issues

INTRO

Team builder is a wonderful thing most of the time,however it has some issues at least in terms of player behaivors,

THE ISSUE

twice in a row i have been matched with a pre made 3., both times these people where in a skype call, and in essence exspecting me to do everything they say, i qued for jungle they accepted me as jungle,I get into game and they are refusing to go bot,when i asked them about this they said "stfu jungle is now bot" when I said that this will most likely not work i got "stfu we have been doing this all day and winning its you who is garbage" so insteed of argueing i go bot and get destoryed(obvusly) for the next 20 minutes it was just the pre made three spewing venom and hatered at me,despite it basicly being their fault.

this happened twice in a row.

HOW THIS CAN BE FIXED

Im sure that if they where not trolling they where playing there own strategy which is fine, however i do NOT like haveing to unwillingly unknowingly be forced to participate in said strategy.

The system needs to be overhauled as not to match solos with premades this can only cause probloms. I was not informed at all that they where premade, no one said a word about a none meta strategy,and i had a horrid exspreince not once but twice in a row. If this keeps up it WILL drive players away i guarantee it.
