If this game was not set in the Star Wars universe you guys at CG would have barely any players left with this sort of game design and game play quality. One month has elapsed since the first release of the Yoda event and yet you have not found it adequate to adjust the fight based on the 5 jedis team composition? If you are that bad in game balancing and AI coding then you should have the intelligence to make it clear and restrict the Jedis that can be used to those that have healing capability and no self buff. Saying that any other jedi leveling and gearing is pointless would prevent your player base from reaching extreme frustration.
This is not even a challenge. The only challenge is to have the right Jedis ( Barriss leader being almost mandatory to avoid 2 shot sequences ), to restart until facing yoda and Barriss, or to have done the challenge when it was bugged with the broken Anakin. After that it's a 100% RNG waste of time that provide absolutely no satisfaction to be played.
