Zeta Ability Materials

So when Omega Mats first dropped, it wasn't too long before we had the initial events that allowed us to farm one Omega Mat per event. Do y'all think we are going to get one of those or a better way to farm Zetas anytime soon? They take a bunch of them and the cost quite a bit from the Ship Store. Once more of the elite Ships players start Zeta'ing their arena teams we should expect the non-elite's to start whining about some toons being OP. We are already experiencing a little bit of that with Barris and Jyn's leadership.
