So I just wanted to warn everyone about using any exotic shards.
DO NOT USE EXOTIC SHARDS YET!!!!!
You will need them to your current exotic weapons from Xur.
Basic rundown of the new system.
Step 1. Get 7000 glimmer, and an exotic shard.
Step 2. Go to Xur.
Step 3. Pray to RNGesus that he has the gun you want to upgrade in stock this time.
Step 4. Pay Xur 7000, and an exotic shard, to get your weapon reset to 0 upgrades, yes 0 upgrades.
Step 5. Now we regain all the experience we previously gained for our exotics, and now we have maxed exotics again.
So if you read me right, then you understand that you can upgrade your Ghorn for example, only if it is one of the weapons that Xur brings with him that week to let you upgrade. Then Ghorn starts with 0 bubbles filled in, and that to upgrade Ghorn you actually need 2 exotic shards, not 1.
I don't like this at all. The requirements are not the problem for me (although the internet is pretty pissed...), the problem for me is that we have to hope Xur brings the gun we want to upgrade with him that week. Good luck on Hawkmoon PS users, since as I understand, Xur is synced to both platforms, same as Nightfalls.
This is pretty outrageous imo. That sweet gun you've got, is now useless, unless you upgrade it, but you can't upgrade it because it isn't in the randomly generated list of weapons Xur brought with him for you to upgrade. Oh well your loss, try next week when Xur brings Ice Breaker for the 2nd week in a row.
