Though I personally prefer the look of the relic armor for my job of choice over artifact, I just don't see myself bothering with whatever process you'll be putting in place to raise it to 119.
Basically, looking back at what you've done with the artifact armor it seems we'll be heavily encouraged to first upgrade our relic armor to the +1 and/or +2 versions first. But with regards to the +1 version I'll be damned if I spend Dynamis currency on anything but a relic weapon. And my personal experience with the "Forgotten" items necessary to upgrade to +2 is that they are too annoyingly rare a drop, to the point where I am still well shy of 30 of any one type of them (let alone 50) after all this time since their introduction.
Really, I'm not sure relic armor +2 was ever comparable to the effort-to-reward ratio of empyrean armor +2.
So while it's nice that you're introducing some sort of path to upgrade relic armor to make it a viable choice today, my experiences with what "relic armor upgrades" have meant in the past keep me from believing that whatever you have planned this time around will be something I'll want to do.
