I didn't say that using parsers to compete with each other is a bad thing. I do it all the time. It's fun taunting your friend when you outparse him, and being taunted when he outparses you. It's fun and it drives you to do better.
I was only making a point that some people dislike parsers because they think its only purpose to to create a DPS contest. They don't see the other purposes and benefits of parsers and that's why they think they're pointless.
The rest of your post accurately describes what I'm trying to say. Thank you!
