Now people are using marks of sargeras, sunfury signets, relics of ulduaar as level appropriate to level their guilds, which is NOT exploiting.
My guild used the Marks of Sargeras to level from 19-25 between Sunday night and Tuesday night. It was only 3 of us running Shadow Labs to get them, I personally did almost 40 runs through SLabs. The issue is you need a level 68 toon that has chosen the Aldors to turn them in.
