You know what would be cool, to level up old low level gear to have a 30-33-36 light lvl and a reforge on abilites or new ablilites. Why? Most of the old gear look really cool compared to the Legendery gear. How would you upgrade? This can go many ways but I think that to obtain light you should add light attributes. Like Motes of Light, other gear with the desired light lvl, Glimmer and such. For example a warlocks chest piece name Axiom Coven II, can be upgraded to have more abiliteis and have light attribute of 30 with 30 Motes of Light, a warlock piece with the light attributes of 30 and Glimmer plus maybe a last upgrade node for these type of upgrades like the Exotic's level up to tier2. There would aslo be a process to upgrade the gear. Like the Husk of The Pit, which has a single ablility note with a upgrade that evolves it into a better weapon. Only thing is you'll have the regular upgrade nodes with the final node to evlove it. I think that if this was a feature you would be able to do you will be able to have many guardians being able to be a unique one . You'll have a guardian in your stlye. You won't have 16 guardians in the tower with the same raid gear. On that note, this won't be a unfair way to obtain lvl 32-30 because youll first need to work/obtain a gear peice with the light attribute. So for an example a new person would have to do Vanguard/Crucible ranks to get 30/33 light armor or VoG for the 30 light armor or Crota's End for the 36 light armor. In the end you'll be a guardian with a stlye diffrent from others and show others how much determination you put in the gear.
