I'm always fascinated by people who don't like a game spending so much time and energy on that games forum. Look you don't like how the game turned out, and I get that. I even get being pissed enough to put a big post on the forum before going back to wow, but I don't get staying in this thread and arguing with folks who disagree with you for 42 pages. It's not something a well adjusted person does.
I strongly disagree with your assessment as well. What will determine if this game has a substantial population in 6 months to a year will be how well the end game content functions, and how well they are able to push out more good and bug free content. Making a functioning and meaningful reward system for world PvP would also go a long way.
Whether or not the UI is as polished as possible, whether they have auto attack, and whether or not they have a LFG engine are really rather inconsequential. There are as many people that hate these features as there are ones who like it. Personally I am ok with the stock UI, and I despise LFG dungeons and auto attack (a combat system with more active control is always better). In any case only time will tell the fate of this game, and the determining factors will not be the ones you listed in your OP.
