It is not ok to charge a premium for the expansion if things are not working 100%. I have been trying more and more of the ED system as I have been leveling toons, and am finding more and more that things are not working properly. I do not accept this in other facets of my life, as I am sure others don't as well, so why should Turbine get a pass for releasing a broken, buggy expansion despite charging a premium for it? Here we are, 2 full updates later and several patches and we still are talking about thing from the expansion STILL not working. This is ridiculous and you should be embarrassed considering how you self-promote when those stupid developer voting contenst roll around. Maybe a magazine should start a worst development contest and see how many votes you get for that one?
I don't mind bugs when the content is free, but you decided to charge a premium for the expansion, now it is time to live up to your obligation to provide a working product for the money you charged and collected.
