This are heroes that I love playing and am very good at based on win rate.
This are heroes I also play well, but I might be (slightly) less good on them then the above.
I am decent on them, but not reliably winning.
Not Good Enough Right Now
I am not good enough on those heroes to make it worth playing them (yet) and/or I don't like playing them or I have not played them for a while.
No experience with them yet or I need to pick them back up after not playing them for a while.
