Sadly, even mentioning server firsts brings out the people who think that being competitive in any shape or form is a bad thing.
You can enjoy being first to down anything, but its already been done in beta so basically no one playing now will get "first" anything. Lastly, no one cares about you or knows you on the server except the people in your raid or guild. Me knowing you did something is unwanted spam.
This is a wonderful thinking process of entitlement that was given life in WoW and will die there along with arenas.You can be competitive all you want, dont need my screen spammed with your game accomplishments though.
