Yep that's how I see some of them now for nightfall/CoE. Bad juju for super week, Monte Carlo for melee week, and no time to explain was great for precision week especially when juggler was on. The same for armour, the ones that give double melee/grenades are great for that as well but there are so many wasted exotics with weak perks. Alchemists rainment is a wasted exotic on the whole for example.
