Really, another person just wants to be able to leave a team event without impunity?
Here is how you never have to worry about it, don't run queues games, do all missions with a set team, private matches, etc. Do this, and you never have to complain again.
If I had my way, you'd lose not only an hour, but an hour account wide, and a dilithium loss double the value for the mission for leaving the STF.
So you're going to continue to punish people that see when it's a failed attempt, thereby making even queuing for an STF a pointless endeavor when the risk and rewards are considered? After 3 lives lost, we should be allowed to leave without penalty.
