And therein lies the problem. When Bungie did their balancing they favoured Exotics way too much over legendaries. That's not balance, that's a (forgive the metaphor) proverbial lighthouse in a storm. People see it above all else and will naturally gravitate towards it because it works better than what they have/had. Was the same in Vanilla Destiny...SUROS ruled Iron Banner. Then it was Thorn...then Pulse Rifles. Difference with PRs was simple...it was just Red Death and Bad JuJu doing all the work - there were a few others in the mix also that were used heavily - more legendaries able to compete with the exotics as it were.
