I actually just posted something similar.. But I actually has SOME technical things xD

1) Multiple different error messages all stemming from a world being full

- No queue system and no afk kick system. The company wasn't very prepared. Adding more servers will only make more servers just like the current state.
Not once have I seen a post about a queue system OR afk system in place.

As of now WE:

Login, click world/character, login/denied and have to spam from MAIN MENU.... ANNOYING

Other MMOs we:

Login, may get a queue, it'll state we're 93 in queue for instance... wait for afk system to boot afkers and wait for people to log off. Takes almost no time and you're seamlessly playing.

2)World capacity being very small for such an anticipated game

-I haven't seen them add anything about increasing it, only adding more servers. If htye add more servers.. when the hype dies down a bit, there are going to be a LOT of dead servers and a LOT of pissed off players. IE Look at WoW when they added like 12 servers then decided to give free xfers... those that went got stuck and complained nonstop then transferred back... NOW they have to add virtual realms so these dead servers don't just perish because kids quit so they don't have to pay $30.

3) This is pretty covered in my #1 No login queue, just a message stating it is full

- To reiterate... The spamming nature of logging in is stupid. I haven't had to spam login since Diablo 1. There's been queue system since mid 1990 s or slightly after. WHY ARE WE GOING BACK TO INFERIOR METHODS IN A MORE ADVANCED TIMES?

4) I'm taking my own twist to this.

- Their website is crap to follow and navigate. Let's face it.. from a design perspective, their webmaster should be FIRED. Never have I ever been so confused navigating through a website and jumped through so many hoops to play a damn game. THE DESIGNER...SHOULD...BE...FIRED. Simple Yahoo! website templates make more sense than some of the crap I've encountered. IE: Look at posts (not on here) on the other SE forums about people needing help to navigate through the system because it was stupid hard! haha
