How do people NOT have enough class materials? Unless you started playing yesterday, you should have more than you'll ever need for the entirety of the game. By now, my titan has 4,000 plasteel and my warlock has almost 1,900 essence. Only my hunter is under 800 wire because I've only had her for just over a month. If you really need stuff that bad, go do Roc strikes until your inventory is full, or run around on patrol, then dismantle everything.
