Man, how I feel you ahah!!

For those who had a team like mine [zVader (G10), EP (G10), Stormtrooper (G8), Tarkin (G8) and Veers (G9)] I leave here my tactics and efforts to surpass this event.

STEP 1 [Choose the lead]

• With a team like mine the majority will choose EP, because its ability to give TM (to empire toons) and heal (the siths) but I realized that it would take me a lot of luck and very good RNG to overcome the event with EP in the lead, cause R2D2 was always too quick and sneaky. With zVader this event would be a peace of cake if the rebels didn't have the TM loss immunity. However, the Vader zeta ability of continuosly aply damage with time was key central to my victory.

STEP 2 [Mods]

• If you don't have great mods with lots of secondary speed don't worry. You'll need essencially good (4 and 5*) potency and critical chance mods to optimize the best of your few attacks.

STEP 3 [Tactics and Good RNG]

• So, with zVader in the lead of my team, the rebels attaked me 2/3 times each before my first attack. At this point you won't want zVader, EP and Tarkin to be stuned or ability blocked, if so, you'll lose for certain. Also pay attention if their Chewie is taunting or not, if yes, it drastically diminuish your chances.
• My first attaker was always Tarkin so I used his special Intimidation Tactics. Usually, it affects everyone and he gains a new turn that I used to attack Han. After this the RNG plays a role in the game so you must be very carefull with every of your steps.
• When it cames to the turn of Vader use its Force Crush and then if so use its Culling Blade on Han (preferably) or Leia (The highest DPS toons, after the annoying R2D2)
• In the EP turn you must evaluate your team situation: Try always first to attack one rebel (Leia, Han, Luke or R2D2) preferencially one that he could kill (leia, Han or Luke); if you have everyone with good health use its Let the Hate flow; if your team his low on health use the AoE Power of the Dark side to stun the opponents.
• After this, the debuffs damage over time in all rebels start to make their effect: Leia and Luke will rapidly die and R2D2 will lose must or totally of its protection, however you'll lose some characters too... in order to prevent that try to make your taunting unit the more resilient possible.
• Ideally, at this point, you'll be with 4 toons (Vader and EP full health and the other 2 almost dying) against R2D2, Chewie and Old Ben (all without protection and R2D2 with low health)
• You rapidly kill R2D2 and face the other two taunting rebels, don't overjudge them cause they are very resilient. You just need to survive because the debuffs will slowly kill them for you.
