Tried SLKR vs SLKR and both team members were impossible to beat forever. See the attached image. Note that the defending team had new DC level 15 for Night vision Rey. Other counters did not work ...
Ideas
You're mirror matching teams that have 100% TM removal, it's the stupidest idea to think that will go well. That's not bad game design, that's bad decision making on OP's part.
Is the DC OP? Yes, but that's not why OP failed.
Jedi DC is promising and I've done Ahsoka testing in arena that is promising. I didn't get a chance to test it this GA cause of scheduling conflict, but it should work, or at least open up a 2 shot.
It’s bad game design. You have a team with an Op datacron that can only be sometimes beat with a non mirror. They did not test any of this. Infinite turn loops is NOT fun and is BAD design .
Good news then, because the datacron isn't permanent. Then will you stop complaining?
