Well we already have crafted gear that is very close to the HM gear. Endgamers usually use the gloves, belts and pants from the crafted set. All you need is find the crafter on your server and ask them to make you the gear. I made full sets for our healers and healers from other guilds, 85 pants, belt, gloves and cape, 87 chest, head, boots and shoulders and they have awesome heals.
I only use mems to buy mats to craft, grassland, rage potion etc . I have like a 1/100 of getting OD and about the same for one good stat, so i don't waste my time with mems stuff at all.
I don't think you got the point of the message. While your method works as far as "working together" is concerned, you're only working with one other person, "hey, come make me some gear". Some people may not want to take that route, AND the point of the actual gear (and this entire thread) is the stats on that gear not sucking. You...don't get current HM instance worthy stats on crafted gear, do you? Additionally, the fact is that mem farming is usually more fun, more enjoyable and less boring when you're doing it in a PUG or at least with your guild and the return of A) Getting gear for an alt that's coming up or B) getting aggs from earlier instances is a plus. It also makes the earlier instances, such as HoS, DL and ZS, viable to run every day because they're quick mem farms, a good party that knows what they're doing can clear all three in what....a half an hour?
