I can already see it happening: someone new to the game who bought the ARR/HW bundle, or someone who bought and installed HW but is still catching up to 2.5's story is gonna boot the game up, bright-eyed and excited. They're gonna sit at the title screen to see the badass cutscene, and have ARR's climax spoiled to them in ten seconds.

SE, please add a trigger that checks to see if an account has a character that has completed ARR's story. If so, then the new HW hook plays. If not, then the ARR hook plays.
