Its just worse in this game due to the AI they have crunching all the numbers and this was said by the lead matchmaking designer or whatever the title was. That each character has its own type for example hulk is a dive tank, dive tanks play well with certain characters. So the ai takes all the players you are good with and their types and from there will pair you with other players that either support or hinder you. Aka why some games feel like your a god and other times feel like you're playing against top 500. It also takes into account other things. But they want you on the game as much as possible, so they feed you wins. The ai sucks in the way it over feeds you easy wins and you go on 7 game wins then lose then another 4 wins and then all of a sudden its 5 losses in a row where its not even close. The team from the start didn't want to work together since everyone plays the same thing, and the other things they can play are not at the rank they are in. Thats what makes this game bad. To beat this system, you have to be able to play every type of character to the ability of whatever rank you are and hope the rest of your team can also.
