How does that effect cryptarch level?

For example, I need 3 different types of materials, and I hve lets say, 300 plastell platings and 5 sapphire wires, to easily get them, I transfer the armor engrams to my hunter so I can decrypt them to get sapphire. If all of my characters are titans, the i send all engrams to one titan and level up faster. At first its hard getting material but later is not that hard, but i have a warlock, a hunter and a titan

It's never hard to get basic materials. Like ever. In the game

When u are just developing a new character basic materials dont fall from trees you know...
