OP yes Trag single target damage is way above Pest. But that's about it. The thing with Pest is that it destroys trash while you're sniping elites which is important for clearing high keys while also ensuring max crit on targets which diminishes the gap between pest and trag's ST damage. 90 is not a great measure of set power btw. It's kind of like the new 70 for most classes after the balancing act blizz did. Trag was really good a year ago when all we did was snipe elites and yea it's defense is easier than say Pest but both play similarly except you actually care about grouping up trash to slaughter alongside your elite target. Hope this sheds some light on why the change.
