I pre-purchased the expansion for early access, I'm paying for the subscription, am I not entitled to the service?

Yes, they did say there will be difficulties at launch (shortly before the launch). However this doesn't change the fact that they failed to address these easily foreseeable difficulties within the ample time they had. They didn't even bother improving the queue system following their failure to increase server capacity. So here I am, writing this post as I babysit my login queue in case it gets sacrificed to another 2002 error.

They're giving more subscription time? Nice. But playing requires my actual time too, and it's not something you can spend, replace and restore like subscription time. Not to mention the issues won't suddenly go away in the next week. They already screwed over many people by pushing back the launch date. Looking back, I wish they pushed it even more considering how these problems spoil the experience.

The original post may be worded poorly, but the criticisms are very valid.
