The only advice I can give you is that you should work on explaining your scum reads and reasoning a little more clearly. I could understand what you were saying in the GY about Bart and it was a relatively good point but it was a little fuzzy for everyone else to understand.
If you have over 4k you can still join ranked training lobby games but you stop getting hearts for training lobby. So after you use them all up you have to either play comp or play unranked. I was just using up the few extra ones I had left. :)
