Add Zeta Tier to Omega Event
Omega events were great when omega's were super rare, but now they're available in many areas of the game. Zetas, however, are still uber rare, and the number of new zeta abilities is increasing fast....

They should add at least 2 more tiers. More difficult and more Omegas. A Zeta challenge for squads would be great but naturally has to be extremely difficult.
