Ranked feast is...

[Yatsurugi]

This is my first ranked feast season. I did practice in 8v8 before the season started and looked up guides to know how stuff works. Made it to silver and that's probably where I'll stop.

It's fun and great when you have a team that knows what they're doing. When you have a team that does the stuff the OP says though, it's really disheartening because you can't do anything about it. You just have to hope the other 3 random people aren't there to waste your time.
