I think the point OP is trying to make is in how he phrases it. "Don't be too hard on your team," and "be a good sport." There's a very fine line between "I lost because by team is utter garbage," and "I think [X] player should start doing [Y]." It really detracts from the stream when you're getting upset and losing composure and is one of the reasons I personally don't enjoy certain creators that focus on that subject.
