Haha, well my friend and I got tired of waiting for people to reply to us so we just did it ourselves today, took like 40 minutes with our level 46's but we did it.
Me and a friend of mine need help getting the crawmerax achievement done... were on our first playthrough level 46's, yeah i know not a good idea to try it at that level lol. but neither one of us really wants to have to do everything in the armory over again just for one achievement and would appreciate any help you could give.
