This is the main reason why I said silent majority. I think the "casuals" you are referring to, blowing up WoW forums, are actually in the minority and benefit by being really loud. I think this scares a lot of devs into thinking that more people feel this way than actually do. I think most people play the game to play the game and loot is just a nice bonus; a means to an end. I think a great example of this is Blizzard's DIablo III. At launch the game was the best selling ever and everyone was excited to get their loot and get their dungeon crawl on. But people soon realized once you played through the game once or twice you've basically done the whole game. You can spend hours and hours grinding up the best gear, but a ton of people just didn't care too. Active players in Diablo dropped off accordingly. If people had the urge to get shinnies as bad as the WoW forums make it seem I think Diablo would be way more active than it currently is.
I will be honest, I came up with these ideas while hoping that Bioware would not make the same mistakes that drove me out of WoW. The old republic is not wow and it never has to be. WoW had the luxury of being the first of its kind (and no forum trolls I am not saying wow was the first mmo). People have years and years of ties build in to WoW. Doing exactly what WoW does is not the answer. The answer is make this game its own thing and say the hell with what WoW did. Innovation is bred by learning from other's mistakes while not imitating their successes. Developing swtor with the same principles as WoW has not worked as well as people had hoped this far, why keep trying to copy them now.
