It's always a mistake to have one valid piece of content for your end game. Especially when your product has been out for over a year. I wouldn't mind if they upped all the gear drops in the heroic strikes to 320 and just made certain perks only available through the raid. Then there'd be incentive to raid to get the really killer perks like white nail, firefly, luck in the chamber, ect. But at the same time you could still have a totally chill experience hitting the max light level by just running some strikes and shooting the shit with your friends.
