I have played Wizard 101 since Beta and enjoy it thoroughly.
As a high level, I like to sometimes help newer Wizards work through the game. Unfortunately, standing in the middle of the Commons and asking if anyone needs help seems to create chaos more often than not. Also, it can get confusing if one just stands around the blue instance circles waiting for someone who needs help with a boss.
It would be nice if there was a Community Hall or Inn or something of the sort in each world's common area where players could go to try to match up for quests. Friends are not always on a the same time so it is sometimes difficult to put a group together for the more difficult boss fights.
