My thoughts.
1. The update was not horrible, that said challenges in particular are what is driving the rage.
2. Protection & Damage Tuning
The Good: No more one shots. In Time, we will see many viable strategies in the arena.
The Bad: Time... 5 Arena battles and 2 Draws. Either more time is needed or damage was tuned down a bit too much.
The unknown: Which Character got nerfed/buffed? I'm willing to take a wait in see approach. It is very hard to tell at this point.
3. Ewoks/Omega: Yay
4. Challenge Difficulty: When players rely on the same monotonous challenges for daily progression, they are already a grind. Adding time and significant difficulty to them is not really welcome.
5. DS/LS/GW - Haven't played yet, but am worried about difficulty AND TIME investment given the low damage rate of toons.
6. New Health meters stink.
Bottom Line: When people ask for MORE CONTENT, they really mean they want more versions of PvP that will essentially give them the ability to have unlimited play (without crystals). What they don't want is time/grind added to essential progression based activities.
