Holà,
Just a little suggestion here, I think a channel "rate my team" or "help to build", could be pretty interesting for beginners (also for more advanced players), they could show what they builded, and the community would answer how to improve etc. That's also a way to share some sample teams too, when you don't know what to play, you've literally no team to begin with. No offense the current samples teams are pretty outdated and will (almost) never lead to a positive winrate.
I don't think that's hard to implement, and that could be a cool feature !
