I'm a big fan of they way BI deploy beta patches. I have to be, I was one of the proponents of it!
But I'm less keen on getting 3 betas in 2 days. This happened a couple of weeks ago and we've had two today and one yesterday.
I appreciate that if a game breaking bug is found in a release beta, you are well advised to push another one with a fix out the door quickly, but this does make issues for some of us.
My GSP, for example has to manually install betas and they get a bit pissed off when they get 3 emails from me in 2 days asking for an updated install. The large download sizes might be an issue for some users on limited data quotas - I remember some South African users saying they had to ration their downloads for this reason.
I do participate in as many of the betas as possible. It's important for BI and us that these things are tested fully by as many people as possible, but if it becomes a hassle for my GSP, they may not install them and that leaves me out of the beta loop.
So, guys, please can you not spam us with betas. You can have too much of a good thing!
