This is pretty much the worst patch yet. The few added bonuses are pretty pathetic (admittedly, I haven't used the Group Finder yet, but most of the Legacy add-ons are too expensive to be worth it), and it gave us more new bugs than 1.1 and 1.2 combined.
For instance, when I am doing PvE on Ilum, what frequently happens is that one of my enemies gets an upgrade that makes him all but invincible. He becomes invisible, I can't detect him, I can't damage him, even with AoE attacks, but somehow, he can damage ME.
Also, the nerf given to Shadows/Assassins was completely unnecessary and extremely detrimental. I've now died more times on Ilum than in all the Chapter 3 worlds COMBINED.
On top of all of this, lag is now worse than ever, and that's saying something. This problem is compounded by the fact that the arrow keys are ridiculously oversensitive (don't play dumb, BioWare, I know for a FACT that I'm not the only one complaining about this). So, could we please either have something done about the lag, or have a feature added in the settings allowing us to adjust the sensitivity of our keys? I understand if the former is difficult, but really, there's no excuse for the latter.
