Myself and 2 good friends grinded the dreadnought for a good 2 hours to hunt for the hadium flakes. We all got one and guess what - they're amazing. (I went for the arc version) I would rather have had one of these rather than a Gjallarhorn in year 1. So yeah. How many other guardians have managed to get a sword? :) Edit: Thank you all, for over 300 comments.
