I thought you needed to purchase those. You throw 4 of them in the forge to get the legendary precursor, no?
The issue is that I don't know what's tied to achievements, what's tied to crossing divisions, and what does or doesn't get reset at the end of the season. The vendor even has 3 of the back pieces locked and I neglected to find out if they get unlocked for purchase through achievements or divisions.
You do need to get all four back pieces and combine them in order to get the legendary at the end, yes. For now, don't spend any tickets and let's see what achievements provide in the higher levels.
I know of that site but I was hoping people would have some suggestions. I liked s/f fresh air ele before the patch and that wasn't a meta build.
Honestly, elite specs are the new hotness right now. I'd take the top elite spec from Metabattle for whichever class has your favorite elite, and make a few modifications.
The most important parts of a build are Amulet and Trait choices. You can copy those as a base and go from there. Runes and Sigils matter, nowhere near as much. And I'm reiterating this because honestly, the elite specs are fun. The only weak spec for pub play is Berserker.
Me personally, I'm currently using a custom Reaper build with Spite and Blood Magic, but it took a lot of time and a Marauder's Amulet for it to get good. It makes me wonder what will come out of the other Amulet additions.
