Honestly, there are 2 main issues as far as I'm concerned.

1. The fact that sometimes when I try logging in I get put into a queue and other times it just gives me the world is full error and I get thrown back to the start screen.
2. There is currently NO AFK TIMEOUT.

I truly wouldn't be upset if I tried to log in and instead of being thrown back to the start screen where I have do click start, choose my character, then click login again...I was just put into a queue and could just leave it waiting in queue while I did something else. Honestly...even if that queue was 1000's of people and I could just let it sit in queue and then go play a game of League of Legends or something, I'd be happy because I'd know that I was eventually going to get in.
