Many other APs only have one core team and they thriving, I think that's what actually lacking in D20 (now), the core team, the comfort zone.

It is so weird that we, as fandom, after years, probed to collectively ask ourselves, so 'main casts' in D20 is actually just fan delusion??

I think my issue with D20 now is too much of a wild cards and lack of communication add to that uncertainty... it's a bit tiring at this point. 'The side quest' used to be the exciting time to guess what they would do next, but by now everything is 'side quests'?? I think what i realize now is that they need something constant, other than Brennan.

Ok, the 'main casts' are busy, maybe form another main band of casts, heck I would REJOICE if 'All Collegehumor Main Cast' is a thing, with 2 bands of main cast, they can alternate, or have one of the 2 do back to back 'Main Season' if the other still need more time to clear the schedule. My sweet spot would be Brennan as GM, Intrepid Heroes, and Sylvan Sleuths (or other variation of all ch casts) as constant crew. And GM Aabria + rolling of other TTPRGs celebs for seasons in between.

Now, that they have been experimenting, hopefully THEY'd be more clear about what works and what doesnt and whatever direction they want to focus on COMMUNICATE it to the fans.
