Well, let's all have a seat and talk about the release of the Beta client. It could have gone better, let's face it wasn't great when it came out. I'm not sure if anything actually worked. The key problem according to those developing it was the lack of testers. Probably true. I myself didn't test the beta client and I don't recall anyone I know doing so either, at least if they did they didn't mention it to me.
I recall a few mentions of no one ever being on. I brushed this off when I read it way back when. I don't pay much attention to aeolus considering the amount of dickery that tends to go on in there. However now that I think on that it may have been a bit of a mistake to just passively leave the testing to individuals. It may have been a massive pain if a person just came on and couldn't join games or do much of anything because there was no one else on at the same time, at least on the beta. There is a small amount of players that pay attention to the news and probably an even smaller pool that actually act on the content actually contained. So say if 50 players decided to test the beta, sounds good but if they're spread out along the timezones and have different jobs it plays havoc with the actual testing. They may not be online on the same day or the same time. And maybe because it becomes to much of a problem to even try, they give up.
Another thing that could have confused people was the the two Betas you guy were running simultaneously. It got me at least. You ask for help with a Beta but you had the client and the gameplay one. If you just said beta and a person only knew about one they would assume that it's that one. Even if you differentiated it by saying gameplay beta or client beta, a person may just pick up on the word beta and assume one and the same. Not everyone notices the difference in jargon especially if they're not versed in it.
Another thing I feel may have hampered testing is the news system. The announcement asking for beta testers was only made once and was only on top of the pile for two days. Then it got buried under an increasing pile of Tourney announcements, FAF development school and the gameplay beta news. Maybe repeated requests would have gotten more attention. An explanation of what the testing might have involved might have helped differentiate it from the gameplay beta and got more people interested. People might be more brave about trying it if they knew what they were expected to do and/or the requirements.
If you're going to do this again perhaps you could put a little more information on the Betas in the news, organise some times for testing and be more assertive with the news on the development you want us to see. Or anything else you think might be helpful.
