add a new token dropped, receive 1 for every completion of old raids, (limit amt /week...idk maybe ..maybe not depending on the amount needed i suppose)

add vendor that sells new mounts , glamour sets (not just a couple...I mean add many!!), minions, furniture, hairstyles, emotes, all in game rare dyes etc (with a cost high enough to ensure a decent amount of participation is needed but not soooo extreme ppl dont "bother")

Something like that is the only thing that would entice me to redo any of the old raids. xp?..nope not even close enough of a lure to me lol, at least the vast variety of items to be bought would entice a more varied group of players that may even consider redoing old content.

I think its a far more enjoyable reason to redo them as opposed to adding a weekly for a gear item upgrade like our past weekly had. (but thats just my opinion )
