GL Leia tier 1 is next to impossible after relic delta update

I just unlocked the ability to do the GL Leia event and tier 1 is next to impossible. You borrow OG Leia but she comes at Relic 0/Gear 13 and puts her at a -7 Relic Delta for the event. R2D2 cant tank all the exposes that the stormtroopers do, even at R8. 

The next tiers aren't bad, in fact easier with Relic delta because you use all of your own units so they are at or higher Relic levels then the opponents. If we could get a borrowed unit at R7 or even r6, then I think tier 1 would be just fine.

Thanks for reading CG.
