I saw a post the other day where someone mentioned about having an inactivity warning, as they were in a strike waiting for the other two members to finish a public event and then got kicked for inactivity. Well i have just tried to do a Heroic strike, and for some reason the game [u]never added a third member[/u], so myself and the other random carried on, wiped at the boss the first time and were waiting for our supers to recharge and BAM kicked to orbit. A 5 second warning on the screen would suffice for me to move the character. To prevent people abusing this, maybe the warning should only appear once (as a reminder).
