I hope you stub your toes very often, every day, for the rest of your lives. That's all. Edit: Just to be clear, I speak about those people ignoring/skipping champions and ONLY the champions. They are important to the rewards granted on completion. Not killing all champions in the strike means less good loot.
There should be a really noticeable UI feedback on Champions. If you skip one it should make a 'fail' sound like it does in eg Dared of Eternity if a timer isn't defused in time. Along with a some text pop up. The point being some players don't know,. Alongside that a visual list of checkpoints for each Champion: • • • ° (missed Champion) • That would be really helpful when you get thrown into a NF mid match. When you arrive you should be able to immediately see if they've already skipped or missed Champions. Otherwise you can be utterly wasting your entire time without knowing about it.
