Ahahahaahaaaa. Thank you! Slightly.......ehhh who am I kidding...very off topic but in a youtube comment under a vid about MMOs I was basucally called a retard who can't speak english (I have a degree in english so that can't really be possible) for thinking positionals is a word and since I think people call these things positionals apparently I also don't know a thing about the game.

On topic: as Xlantaa said, most mobs die anyway even if you don't do your rotation properly. And you'll get that new cross-role skill later.
