This post is about the class-specific upgrade materials you get from, and need for, armor: Hadronic Essence, Sapphire Wire, and Plasteel Plating. [b]The problem with them is that in their current state they are either virtually nonexistent or infuriating.[/b] I main a Warlock and I have almost 1000 Hadronic Essence. My other two characters are a Titan and Hunter, and I am at the bottom of the barrel for Plating and Wire. I have leveled up a lot of armor with them but I've gotten to the point where I can't upgrade my last remaining exotics because I have to grind two or three Roc strikes for a single node. Now I enjoy playing the strike playlists from time to time but this has become very annoying. It means that I am not leveling up alternative pieces of raid gear not even because of the relatively scarce Radiant materials, but because I don't want to have to grind strikes only to be back to zero Wire or Plating again when I'm done. It also means that I feel pressured not to play with my Warlock because he has more Essence than he needs. [b]No one wins in this situation. It's making me enjoy Destiny less. It punishes people for having three characters of different classes.[/b] Here are some solutions that shouldn't be difficult to implement: - [b]Trade one class's materials for another[/b]. It would be great if I could trade Hadronic Essence for one of the other materials at the Tower for a minimal fee or no fee at all (or else you're trading grinding for grinding) - [b]Reduce the materials required for armor upgrade nodes.[/b] Self-explanatory. - [b]Have armor upgrade materials be purchasable from the Tower with marks[/b] This follows the precedent with the other materials you had to farm previously. That was a great move. This would be as well. - [b]Increase materials yielded by breaking down uncommon or rare armor.[/b] This is my least preferred option but it would certainly help if green armor yielded ~5 mats per piece instead of just one. Needing twenty-five green armor drops to get one exotic or raid upgrade node is a bit excessive, don't you think? Thank you for making Destiny. I enjoy it and would enjoy it a lot more with less arbitrary barriers to enjoying new gear. For players reading this, please bump if you can relate or think it's a good idea.
