Different strategy for blue / purple side

I think it would be really useful because creating a good draft for both sides forces you into being safe and banning op champions because if you don't, you'll get fucked 1 game out of 2 (purple).
Also, it could be cool if we could choose wich side to play in in sandbox, for example if you have an upcoming league game as purple, there is no way to test your draft against your opponent.

Honestly, I think it should not be possible to do Sandbox against people in your own league. Also, Sandbox games should not be visible to other players.

Perhaps a setting where you can allow other players to view your sandbox games, but those are like Scrims to me. Obviously in the real game people can see ranked and league matches, so keep that view-able, but everything else I'd say no.
