Then Jesus, call it DD. What's stopping you?
Now I know you're being serious. Who cares?
We all know what it means anyways. Someone who deals damage.
If people don't know go "DD = DPS" or vice versa.
You're not going to force people to say a term that you prefer.
Just like when people say 'Toons' [And that bugs the askdjkasdjk out of me]
I'm not going to tell people to say characters. Not that big of a deal guys.
