This game has a huge amount of growth potential. It's Star Wars. And that is why I stay.
WoW has run out of lore (Panda and Pokemon time!) and has dumbed down everything to the point that it's an unrewarding experience to devote time playing. After so many years, there are a lot of nice-to-have things that Blizzard put into that game. There are also a lot of really stupid dumbed down god-awful systems. We can only hope that Bioware has the ability to look at other games and pull in what works, and leave what doesn't.
Content is key. Tools and systems are things that can be put into place and worked on over time. These are things that you know will get better as the game develops over the coming months. But you can look back at Blizzard and their current xpac of LOLs and then next xpac of LOLs and know that the content in that game is done. Regardless of some well-refined systems that work ... the story is stupid, the game is uninteresting, and the ridiculous rehashed boring content that is there - is dumbed down to the point that an armless child could headbutt his way to heroic tier.
