Melee classes are sad in CC

If that's all you're going to do, then you're wasting your time and everyone else's.

Do you actually think Protoss players spend time playing Terran and Zerg at a professional level, that they need to do so in order to have an educated opinion on balance and design?

They absolutely do...

Just like pro players in fighting games spend an insane amount of time in training mode looking at frame data and learning what can be crushed/throw punished/strike punished.
