Test server. No thanks. Let them have closed test servers in house, or through private means. With a Non disclosure agreement. Don't need the public eating all the content before its released. If it is broken when released then we can speak with our wallet, if it is not fixed in a quick manner. I know MMO's have a tendency to have errors, its how quick the devs respond to those problems that holds value/and if they can minimize those problems upon release. MMO gamers are probably the most versatile gamers of all gaming, our methods of use can only be guessed at best, even if they try to force a certain mechanic, the community will find other means of using that content. Basically we show the weakness/strengths of the system/content they have in place. Real world testing is unpredictable. Many players develop outside of the box tactics that developers didn't even assume was possible. Sometimes they just write poor code or conflicting ideas that don't pan out the way they envisioned.
