So I decided to delete my second warlock and make a hunter, finally. My only problem going in was knowing I was gonna have to grind out some sapphire wire to be able to upgrade my stuff quick. So I found a sure fire way to get class material cheap. If you have access to the vanguard armory "the pre order bonus green guns and helmet you can buy" then you're in luck! The vanguard sells a class helmet at 250 glimmer, if you dismantle it then You get at least 1 class material, maybe 2. At the rate of 4 per 1000 glimmer you have have 100 material for every 25000 glimmer, maybe more if you get 2 every one in awhile. After you add up about 300 class material this method isn't needed at your character should be able to hold their own supply from drops at this point. Another trick I used is any engram drops from my warlock or titan I would give to my hunter through the vault. Hope this helps!!!!
