I just ran a 1050 Ordeal at about twenty minutes. I got a single Enhancement Core. I did the four daily gunsmith bounties for four Enhancement Cores in about six minutes.

I know they want upgrading and masterworking gear to be an ever present consideration, but seriously, what the fuck. In what world does that make sense?

In a world where they determined that needing Enhancement Cores to infuse weapons and armor was a frustrating system so they got rid of that...and introduced Enhancement Modules to do the same exact thing. Then moved Enhancement Cores to an even more convoluted system.
