For those wondering about Participation Points...
If your team wins 2-0 (or loses 0-2 - apply this for the rest of the examples) and you don't play your match, you won't get the round points for participation, but it won't count against your 100% participation for the event. (Although, I think the 3 points would be worth it)
In other words, you're still encouraged to play your match.
The most Participation Points you can get in a round is 3. If you don't play your match, sub for a teammate, and your team 2-0s .... you'll still get your 3 Participation Points for the round.
If you get subbed for, you lose your 100% Participation Point Bonus (so root for your team to go 2-0).
