Was 45 mins, then 10 mins, last week was 18 mins, now it's 11 mins. Revives are supposed to stay after time runs out - now they expire. It's simply impossible in 11 mins solo & 0 revives. Fireteam finder shows expected completion time as 25-35mins, so the 45 original timer was correct, now it's 75% less. Caldera is 11 mins - crazy.
