Well, the timer is fine but it also plays against us if the people you're running the strike with are really good. I've had strikes that only take 5 minutes to complete, if you skip some spam. And the we have the teammates who, for some reason, don't know where to go or are running against a wall (probably just pressing the joystick one way so that they don't get kicked) or just blatantly try to run ahead and expect the rest to pick up the slack. I've always said that one good way to solve it would be to do it like Left 4 Dead did: the teammates vote on kicking members out of the strike. Majority rules, end of discussion. In L4D's case, it worked against you sometimes as some trolls liked to team up kick people off at the very end of the event to prevent you from just finishing the thing. And I can easily see it happening in Destiny too if they implement it. But I think it would benefit people more than it would affect them. As it is, what we've got right now might not be the best method either so it can't be much worse.
