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.
Been through this again. This is still something I wanna look at. Any further ideas? Bear in mind, any ideas that require extensive code is unlikely to be entertained.
