Currently, my premade has won 28 out of 28 WSG games. The average length is 8 1/2 minutes.
I have to ask, if people hate solo queueing for WSG, why not form a group? If you are in a group, go with your friends. If you don’t have a guild or friends online, form a group on the Looking For Group channel. There are always tons of people who want to group up, especially given that this is an MMORPG.
At the end of the day, players communicating with each other will more often win against players who are not communicating with each other. This cannot be changed. You can’t make it so that players with zero coordination have a 50/50 win rate against premades with coordinated people.
That said, another suggestion I have is to use the ingame voice chat. It works really well. It will allow you to make a group via LFG chat and coordinate over voice.
Coordinating with your fellow players, whether with ingame voice chat or Discord, is how you will win. If you don’t want to coordinate, don’t expect to have a high win rate.
