This is the fastest method I've found for class material farming. You can do this once a day and it nets 60-100 class mats a day (60 minimum, 100 highly unlikely, although theoretically possible). it will take you about 1-1,5 hours and it doesn't rely on RNG. Basically, it requires between 12000 and 14100 glimmer to purchase 10 green helmets, 10 gloves and 10 chest pieces from your vanguard mentor(glimmer needed depends on the current price of the items, 400 or 470). It takes you about half hour Exclusion zone farming to get the required amount(6 runs per one Resupply code, 1 run nets about 550 glimmer). Also you need to finish 10 bounties, EXP doesn't matter 2500 will work just as well as 5000. When you've got all that turn in one bounty at a time, switching your helmet, gloves and chest each time you turn in a bounty. At the end, you'll have 30 maxed out green armor pieces, each worth 2-3 class mats. Hope this helps. P: S. Bungie, please give us weapon parts and class mats exchange option in HoW. EDIT: Also if you have blue boots, level them up as well before dismantling. That's how theoretical max raise up to 100 instead of 90. They require 3 or 4 2500 EPX bounties to max out. Don't bother with green boots 'cause you can't level them up.
