Armory with atleast 1 slot til you get it done properly and then add a few more.
But just add something so we can quick swap between atleast 1 build.
Who respeccs at 250+ Paragon? Who is that insane?
And who creates a new character just to relevel 3 new glyphs if you already have 2 in the 45+ range for your new build?
Or at the very least if you are too slow to hotfix an armory:
Make Glyphs a onetime thing like Paragon, share it across all classes during season.
That way we dont have to grind that cra.p again when remaking a char to try a new build
