I think that is a good idea but still not so early. My guild has been doing ssc/tk for almost 2 months. We have never once seen mallet of the tides. We have also only seen fang of the leviathan once. These are top tier items that will not be replaced. If we semi-hardcore guilds can't get these drops then why should someone with 20 bucks get it?
Don't mention trash drops, not a single TK trash drop and only about 1 ssc trash drop. Even after the supposed fixes we've only seen nether vortices and a couple patterns. Still no trash drops. There were plenty at the start but you guys nerfed it to all hell and still havnt fixed it.
It is still too soon. Also tanks dont need anything from the last bosses, so why would tanks even bother? why not just wait til BT since theres not much from hyjal either (only 2 items that are easily replaced).
EDIT: Why would a tank get resist gear if all his bis gear can be bought from the store as well? putting store items out will make any non t-6 guilds have a ton of trouble getting people for ssc/tk.
