Hopefully, we will see some minor improvements to older content in addition to whatever else they decide to add. Slight improvements could be:
1) Tank Raid simmable with the same requirements as Pit (35 Kenobis/50 Victories)
2) Revamp some of the heist events to improve their usefulness such as Droid Heist for late game players.
3) Carbanti Daily Challenge - Change the MK3 Carbanti drop rate to 4-5 instead of 3-7. Like the change to the zeta daily this increases the overall amount of Carbanti's given out, but gives up the extremely small chance at 7.
What I would like to see added resource wise:
1) Gear Heist and Relic Material Heists using ships. This would give ground credits, training mats, and slicing materials, yet give ships ship reinforcements/omegas, gear, and relic materials. A perfect balance as all things should be.
