People have such short memories. Does this bundle suck? Yes. But all of the best bundles in the past few months have been from Humble. Indie Bundles 10/11, Bohemia Weekly, Roguelike Weekly, that Adventure game weekly, Popcap weekly, Sega Weekly, that one a few weeks ago that had like 10 games in it (mostly repeats, but still high quality), and the co-op weekly (again, a lot of repeats, but still high quality), all beat virtually any bundle any other site has released this year.
I've said this before, but the only reason people get so pissed at humble is because everybody has unreasonably high standards, and because of humble's boom-bust. They have a lot of bundles that are beyond crappy (e-book bundles, most android bundles, etc), but their best bundles completely blow everything else out of the water. I'm not sure what you consider to be a "super bundle," but if you look through humble's wiki, they really never had an extended period where they had insane bundles coming out every two weeks. They had short bursts, where they had back to back great ones, but never an established pattern where months of non stop awesome bundles. Their numbered indie bundles are typically at least 3-4 months apart, if not longer. Their high quality developer bundles (WB, Origin, Deep Silver) have too small of a sample size to even discern a pattern from. The weekly sales have always been a bit up and down, although they were more consistently great when the weeklys were first instituted...but there's only so many games to bundle. It was inevitable they'd drop in quality at some point.
The really good bundles aren't further apart. What's making it seem that way is that humble shifted to releasing bundles every two weeks just last summer. Realistically, there's no way they could throw out a crazy awesome bundle every two weeks. It'd be impossible. There aren't enough highly desirable games out there to make it happen. Are the bundles inconsistent? Yes. But let's stop acting like everything humble has done in the past year sucks.
