The expansion is looking fucking good, I don't know what some of you are on, really. Plus, we still haven't seen everything in detail, so wait for the new panel. My only hope is that they will keep adding new races, but I can see 'more customization options' replacing allied races altogether, I say to myself it will be fine if I get a vampiric skin, but honestly, it will be shit compared to having a fully fledged allied race with new sounds etc. So, yeah, kinda disappointed about that, and mark my words, there will be no more allied races, especially any covenant ones.
As for new classes, come on, take a look at how impossible it is to balance, especially in PvP nowadays. I, for one, don't want more classes, just balance the current ones.
