Vanguard has been designated as the "Player's Choice" update, and recently the players decided that it should be focused on bug-squashing. The next phase of this process is now underway, and players can submit their choice of which bugs to fix at this thread. There are a few guidelines for people planning to put in their two cents, the most important being that each person can only submit one bug, and they should do their best to avoid repeating previously suggested ones.
The thread will be open for two weeks, and after that time, a poll will be created for forum-goers to vote on Vanguard's worst bugs so that they can be targeted with priority. When one player asked why the devs wouldn't simply work off the bugs submitted by players with the "/bug" command, Salim "Silius" Grant replied, "This way we are hoping to get the most high profile bugs that the players want fixed right away. Digging through /bug does not tell us just how important or how many people are seeing this problem." If the whole thing goes to plan, a bunch of really irritating bugs should be eradicated when the update rolls out.
