I wanted to point out #2 and #10, specifically.
Blizzard will probably want players to test grief play, to see what holes are in their design.
For example: Dark Age of Camelot recruited entire 'griefing' guilds into early phases of their beta test, because they needed to have realistic test results and wanted to see how 'nefarious' guilds would exploit their rules, restrictions, gameplay features, etc. Most people who pay to play are not going to want to begin testing griefing exploits after World of Warcraft's release...
...especially if they are on the receiving end.
I would also like to take the time to point out #10, because I completely agree with his concern:
10. Get organized , (learn) how to report bugs, and things like this..
As a participant in many past MMORPG beta tests, far too often (almost daily) I have witnessed that testers will not read the 'Known Bugs List' provided by the game developers and will continue to spam the team with redundant bug reports. So, I would like to give a heads up to MoonK(GT. for reminding all the prospective WoW beta testers to save the Blizzard dev team and fellow testers the headache of having to filter through duplicate reports.
It is counterproductive.
