This build is gaining strength now and already did GR100 in season 7.
I am not a big fan of Archon, and strongly think that Archon should stay with Vyr's set, where it belongs. But unfortunately (or fortunately?), Archon itself does a lot of damage and works as a damage dealer for other sets as well.
Surpisingly the gameplay is much easier than it was in season 6, and even such noob as me can get to leaderboards easily ;). I managed to clear 87 without a single augment on second attempt!
