Please remove all premade options on ranked. It's going to be abused by people sabotaging comps and inting to boost their friends.
Sabotaging is a good tactic. But when even a single friend can make it significantly more effective it's a massive problem. And creates a huge advantage to premades.
We'll be tracking how successful premades are, and if premades are a substantial advantage, we can adapt premade restrictions. We're going to learn a lot in the Beta Season of Ranked, and we'll make changes based on what we learn.
