I grinded (ground?) my way to Rank 4 the last time around. I was already @ level 30 with the raid gear, but I really liked how the IB gear looked - not to mention the perks were a better fit for my hunter. Well, apparently I was wasting my time, since Bungie deemed all of the gear we ground (grinded?) out worthless. I'm assuming those that continue to quest for higher levels will have to toss all their stuff when the House of Wolves drops. No thanks.
