If you mean the old ranked PvP system we tried to implement, we've stated several times we no longer have the code, so no. It will not be returning, sorry.
There's requests for Frag Stashes in this very thread, so there is interest. I mentioned potions in my post above, so yeah.
Loyalty Stashes I've asked for. We'll see if it can be coded. If so, I'm happy to introduce a Loyalty Stash that functions like the Mystic (Shard) Stash.
