Crafting lower tier mats?
I don’t know how much it actually effects but I notice that the higher salvage kits say that they have a better chance of giving the higher tier mats, so may be using a basic or even a crude salvage kit would help and save on buy the kits.
Best bet is to look into the different level loot bags lower tier enemies drop and farm them (or buy them on the TP). The level of the loot bag itself determines the materials they generate (not the level of the character that obtains the drop).
