I have terrible coordination and reflexes after a couple of strokes, and I can’t jump, especially if I can’t see what I’m aiming for or the gap is narrow or partially obscured, and yep the mission, the first part of Act 3, starts with a load of jumping… You can say it’s a skill issue, but after ten years in game it’s not getting any better, and trust me, I’ve tried. So, thanks Bungie…I guess I don’t need to worry about finishing the story.
