You do NOT need to run Heroic strikes to get the Taken Archon Priest strike or the shotgun, they can both be gotten on the regular level 36 Vanguard strikes. same with the Omnigul bond and probably the items from Malok as well. Tl;dr- My Stolen Will dropped at 328 from a level 36 strike. Check my Warlock if you wanna see it. I know a lot of people already know this but I see posts asking all the time so hopefully this reaches anyone still wondering. Happy (hopefully faster) grinding :p
