I'm about to come up on my 5 resets quest step for the broadsword and Bungie stated this is retroactive however I reset my Valor rank 5 times last season and have the associated Triumph for that. Does that count or do I have to reset my Valor rank 5 times this season too?
You'll have to do 5 Resets in this season again unfortunately. The Quest was retroactive if you reached the Quest Step for the 5 Resets in the Season you achieved the 5 Resets in. In your case, you achieved 5 Resets last Season, but you didn't get to that Quest Step, so your progress towards that step was removed.
Lockdown is an extremely fast mode for valor, me and my friends can win in less than two minutes
I think this season. I’m Doing the same thing and it sucks.
