I've been having fun with the game since the 3 day headstart. I have one char at level 80 so far, two in the 30s and 5 below 20. I got myself enough slots to cover one character for each class, all the gems bought via gold.
I'm not sure I will reach 80 with all of my characters in the long run, but I know I have definitely gotten my money's worth. Sure I've been annoyed here and there with glitched Skill Challenges and one glitched personal quest, but it's not been enough to drive me away in frustration.
In the court of King Chaos only blood can write its own tragedy.
