Well to be honest, it has been dishearting to see so much negative, but for me the issues that I have been hearing that a persistent are issues that are not related to bug fixes, broken quests, clipping or stuff like that. That is stuff they can easily fix/patch. What concerns me is the "lifeless" that some are reporting and the lack of content in the form of alternate quests outside of the Story.
For me, I love a good story but I also like "other" things to do in a game, especially in an MMO. While I understand that they are holding back on the flashpoints and that is understandable. The real concern is just the lack of what sounds to be quests that are only story bound and not other stuff to do.
As mentioned an MMO that seems lifeless because of the lack of NPC's or stuff going on that is not another player is a bit of a big letdown as well. If this is truly a July build, then some of the technical issues are understandable, but lifeless planets, lack of side quests or just random quests are things that if they are not in now, it may not be at all.
Lastly, even though some stuff sounds discouraging, I will NOT write the game off until I actually play the "official" release of the game. There is so much that happens to a game, even an MMO in the last 2 months of release that anything can happen. Although some of the stuff that people complain about are things that are harder than just adjusting spawn timing's etc.
So, even if this is an early July build, we are talking about 3 months left if they plan to launch in November.
