Maybe it's time to release a new raid instead. As the person above said, tweaking toons to avoid tweaking the raid just has unintended consequences elsewhere. It's been over a year, and the Sith Raid is boring now. Time for something new where the infinite loops now created by new toons doesn't work.
We're probably at the point where ship raids are viable. Battle of Coruscant , release GKs Starfighter (and a battle droid + ship) few weeks before. Prize for the raid is Grevious Capital ship
