Rumor:
Your odds of getting valor are best if you one of the last to die.
e.g.,
kill 5 people, die in the first minute = no valor
hide in a closet for 4 minutes, then kill 5 people and die = much higher chance of valor
Can devs confirm if this is true? If it's false, then maybe we can stop the rash of people hiding in closets for the first half of the fight. Personally I can't think of a time where I got valor without being one of the last few people to die, though, so I think the rumor is true.
If it is true, then I think:
a) Valor should be removed
or
b) Valor should not be based on how long you lived
