Yeah, that's kinda how it's been, but how many of those check back in and play when they see a new update?
I'm willing to bet there's more than a few who simply forget about the mod because of the long stretch between patches. I'm all for the devs taking their time and squashing most of the bugs before each release, but perhaps a shorter, smaller release schedule with less content but greater frequency would be a better model in the long term.
