I agree that there is a lot to like about this update, but the apparent lack of testing really did it a major disservice. Either they didn't know about the bugs (yikes) or they decided to push forward with the update anyway due to scheduling. I'm a little tired of this sort of thing happening over and over in the games world - ship it buggy to meet a deadline, patch it later.
Had to calm a lot of players in my guild that were frustrated and demoralized by the difficulty. Several didn't get rewards. And to make matters worse, the exceedingly-frustrating Thrawn event came back on the day of P1 - when everyone was blindsided by the wave 4 difficulty bug - and all the devs were on holiday.
While I appreciate the devs efforts in supporting and expanding this game, sometimes they have to called to account. If there was ever an update that deserved all the flak on the forums, it was this one.
