Is it true that all purple sets should be boosted rather than attuned? Or is it just the Winter and PvP sets?
Specifically, I want to slot Armageddon, but I'm not sure if I should be buying the level 50 and boosting it, or buying attuned versions. Is there an easy way to tell what specific set should be attuned and what should be boosted, or is it purely as simple as "attune orange, boost purple"?
