Well I find that most people really appreciate it when I blast through the strike for them in 5 minutes (I'm a speed runner.) I guess if someone was failing at speed running it and wasn't contributing anything it could be annoying but, if not, not sure how you could be annoyed, they just saved 10 minutes of your life. If you want to run through every strike killing every enemy that's your prerogative, if I want to run through it, that's mine.
