Still i think what you guys had going in BC was the best platform. Theres no reason to not be able to add hard modes and challenges and scenarios and whatnot with a Badge of Justice currency. Just the 1 currency used for all pve. Dropped by heroic 5 man bosses and raid bosses. And whatever allocation method there is for scenarios. create wow po 1 full set of gear equal to the mid range tier set, just make sure it is at least 1 tier less than the max lvl set. Reserve the true best gear for the hard mode raiders since they work for it. But have this full BoJ gear set purchasable from a vendor. This stuff can be purchased over time by ppl who do not raid/raid little. Or more rapidly as interim fillers for the dedicated raider while they try for thier specific hard mode slot items.

Dont force ppl to use vastly inferiour junk (greens or blues 50ilvls lower) and dont give them freeby stuff aka timeless isle/toc as fillers because they didnt get thier drop/roll
