Beta testing is fun, but it seems to be losing it place in the gaming world. I would much rather have it done by people who are "professional" gamers, than the masses like so many others do. I see too many "Open Betas" that are basically the full game and very little or nothing constructive gets changed, fixed or adjusted when the game officially goes live. I personally do like the way Turbine and a few other unnamed companies test their products. You get a better, complete game that a higher number of people will enjoy playing.
Side note: With how hard it is to get banned in this game, does anyone think they should be considered?
Side note 2: What sucks with playing through Alpha and Beta stages is that you know the game too well. The law of diminishing marginal utility takes hold fast for many after the game content goes live.
