I think its a good thing that they fixed these errors before releasing the content, don't forget they said there were going to roll out 2 patches per month, its my thinking that they will be releasing the next patch in about 2 weeks time, time enough to let players come back and see the improvements they made to the game and get used to the new system and all its improvements, my suggestion to you guys is to come back asap and get used to the game again, it would be a good thing to get used to the games mechanics once again, to level up a little bit more and be prepared for the content.

I am also willing to bet the 2 patches per month will be 1 general improvements and 1 content patch per month, as Ouch! said, its probably not a good idea to tackle both at the same time.
