Many small fixes. Nothing worth noting.

Very small amount of fixes. These are not the updates you are looking for...

The first major update since release. Of note:

• A new level 50 Flashpoint, Kaon Under Siege, is now available for play in Normal and Hard Modes.
• Warzone bracketing system now exists. No longer is everyone lumped together. There are currently two, 50 and everyone else.
• Corrected an issue that caused the indicator that a companion wants to talk to you to disappear. Nothing more annoying than your companion saying he wants to talk to you, so you run back to your ship and they have nothing to say.

Nothing major, just a lot of things. They did change the update system to be more in line with every other piece of software on internet. Welcome!

Update 4 is now on the servers, ready for download. This is a huge one, tying into the Rise of Isengard release tomorrow. There are three major updates that I see. Traits have gone from max level 10 to max 12. Pity to those that stopped at 10! They have added 10 additional levels. Finally, stats are no longer capped at 650...there is no cap.

Read on!
