Just like the Sturm and Drang combo, there should be a set or multiple sets of armor that when equipped, activated or buffed existing perk effects. Equipping these special exotic/legendaries in different combinations could offer a various range of different effects for the right situation. This would afford each player the ability to fine tune their character for their own unique play style. Plus give hardcore gamers something to grind for. There could be an exotic chest piece with stand-alone perks, but when equipped with a certain pair of legendary boots, activates a perk for increased sprint speed when talking damage from a certain element type. Some of the damage is absorbed as energy and funneled to the boots for increased output. The boots could even look robotic and begin to glow/pulse when the perk became active.
