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 ...

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?
