If it takes you an hour to find 50 mats out in the field than your not looking in the right places. After you loot a chest or material node, it takes 5 min before that node respawns. It might show up as a chest or material, but it is always in the same general area. Some areas even have 3 or 4 spawn points in one little area. So, you just need to find a path that takes about 5 to 6 min to circle and you'll be looting nearly non-stop if your just looking for mats. Hell, some chests even drop 5-10 mats at once. The best way to get mats [b]without[/b] running in circles, is to learn the possible spawn points, then just hit them up while running bounties. I can get 50 mats in under 20 min easy. On a good day I can get 50 in about 10-15.
