Also.. anyone know what is the best armor set at the moment? i only saw in the AH is lvl 37 blue gear, and not even complete gear.. so where i get better items than lvl 37?
Get your recipes from your armorsmith master in your capital town. Be forewarned, they cost dungeon points. At lvl 45 armor pieces, it takes a lot of dungeon points to acquire them. So you're gonna need to generate dungeon points either from running dungeons or hunting quests. But then too, many of the armor pieces require mats looted from the dungeon bosses. Only 2 pieces don't require dungeon mats to craft.
So don't rely upon hunting quests to learn the recipes, as you'll also need the mats that you can only get via running dungeons.
