Brand new players should not be allowed into 4v4 Feast.

[Kyani]

One of the (many) problems with the Feast's matchmaking, currently, is that it tries too hard to make the two teams match up - if one team has the best player, it'll also have the worst player to balance them out. But the balancing completely breaks when the "counterweight" player is someone who has little or no experience in the mode at all.

Three players averaging 900 are not going to be able to carry a 0 player against 4 players averaging 675. They are simply not enough better. New players should be forced to play some number of unranked games (or win a smaller amount) before being allowed into the wild, because they are not equipped to handle a 4v4 match, and it creates a huge imbalance in game quality. This gets worse the higher your rating gets, as well - @900, you might have 2 450s and a 0. This is technically carriable if your 0 is a DPS.

At 2000? You'll have 2 Silvers and a 0. You're not winning that short of some absurd luck.

e:

Ranked Feast should require (for example), 10 matches or 3 wins (the #s in Challenge Log). Without any experience at all, you are dead weight and actively ensuring that your team is not winning the game.
