Premades que freelancer option these days. So every GC has a chance to get them. With or without them average win rate is the same so it doesnt provide any disadvantage to a regular player = fair. They may lose against premade but next match premade will fight for their GC and carry them. The only ones who constantly benefit here are premades themselves, but I consider it's a payment for all the extra effort they do, from finding and organizing people to learning and properly using their pvp skills.
Effort should be rewarded, don't you think?
