What do I mean by that? Well no game releases at their very best, as polished as it may look people will always find faults. My point here is that they have all the important stuff, and can easily add new content later on to round out their game, stuff like...
-more raids, grouping, and pve content
-more bgs, arena, and pvp content
-some kind of dungeon grouper
-any class balance issues
-complexity of enemy ai
I had a very enjoyable time in the beta, and was pretty impressed and satisfied with what I did see. There have been some small issues, stuff like "feels like im playing single player in an mmo" or "needs more pvp modes"...but they can all be dealt with in the next content patch. TOR has a solid foundation that they can build on, and as long as they listen to players and try to incorporate the best ideas they will succeed and have a dedicated following.
I absolutely love how unique and different each class is, even though they have mirror versions......as well as feeling more connected to every enemy I fight or item I loot b/c I have a story that explains their purpose.
Too many people want to see this mmo fail, myself included, because it doesn't go above and beyond expectations. But it's a step up from WoW....and with a little work can become a very great product.
