You do know that not everyone has a black belt in MMO's...right?
You could have identified what is meant by "add" or which skills "interrupt" but, instead you chose to do some ego promoting. Which is fine. I'm used to high school kids. But, whenever you are done congratulating yourself for your inner circle lingo and derisively lording it over newcomers let us all know. We'd like to be able to play the game too.
