The fact that paying money does not give you an in-game advantage I think is the best thing about BB and is the foundation of their success.
This is the main reason I became a supporter. If paying money gave an in-game advantage I wouldn't. All the perks are nice though.
The one thing I really like about it that no one mentioned is the no match spoilers. So the results stay hidden in case you want to watch the game later without knowing the result. 3 months of supporter is only $11.99, maybe try that instead of going for the full year?
