I am thoroughly confused by the light progression on armor. I'll use my Legendary armor as an example. I have Leg: Dustwalker. It started as +18 light, is fully upgraded with 5 upgrades and is now +27 light. I have Gauntlet: Ghost Angel. It started as +18 light, has 3/5 upgrades and is at +23 light. I have Chest: Dustwalker. It started at +18 light, has 2/5 upgrades and is +22 light. Assuming all Legendary (non-raid) starts at +18 and can be upgraded to +27, there are 5 upgrades for each and taking the above information into account, I would conclude that each upgrade is worth: First: +2 (alternatively could be +3) Second: +2 (alternatively could be +1) Third: +1 Fourth: +2 (alternatively could be +1) Fifth: +2 (alternatively could be +3) Has anyone figured this out? I can't find a reliable answer on the Wiki's, Reddit, etc.
