It's called "Loot"

...Let's be real though xD

You're a Damage Dealer, you're not a Damage Per Second.

Too bad the game disagrees with you. >_>

If you don't deal damage to your enemies as someone with a red role icon, you do something wrong
DPS is something for parser users

The point is that the game itself calls that class role "DPS", not "DD".

----

I understand where "lot" comes from, but most times I've seen it being used referring to "loot" instead of "casting lots".

(example, "he got got all the lot" or "no lot dropped for me")

EDIT: not saying every single person misuses it, just that it's widely misused.
