Here is my idea ... instead of chasing multiple copies of the same armour piece to get the different archetypes and random stats ... I wish we could just have a mod drop that we can chase and slot into the piece once we collect them. Even if its just for tier 5 armour... Once you get a tier 5 piece, only mods will drop (or in case of a pinnacle ... it can drop the armour piece so you can infuse it)
If my math is correct, there are 6 archetypes and 4 random stats for each. That means for each armor piece of each armour set, there are a possible 24 roles.
After Solstice .. my vault is screaming at me.
(The same solution could be used with the exotic class items as well...)
