I don’t understand why anyone would use these in lower level content. People should just use 3oC in the raid for an insane increase in drop rate as opposed to Vanguard Strikes. The last time I used it in the Leviathan I got two Exotics instead of one from my three locked chests. It’s better to think about when you should use them instead of blindly wasting shards.
insane increase he says ... as a reply to the response from the dev team that shows it's anything but insane ...
