I completely understand where you are coming from Lucre. For awhile now, I've been caught up by the fact that my drafts are missing the mark in a few areas. It's largely a problem of group size and how drafting a fraction of the cube introduces more variance than I want. So you often see great deck ideas fall down at the end because not enough key cards came up. It's not bad per se, just not what I want to see. My expectations have gone up since I started cubing I guess.
One way to counter this is focusing more on less narrow cards. But then that leads to goodstuff.dec and takes away a bit of the synergy focus that I think is very satisfying in draft and deck building. And I think this is what is driving me to try and make a modular cube work. Where you have focused blocks of cards and you can add and subtract them to make the draft pool the size you need without hacking out half of an arch type. In theory, you solve all problems with this method. You have variety because you don't draft your entire cube each time. But you keep the focus on synergy because the pool is still very focused by the nature of how you group your modules.
I'm finding it exceedingly difficult to build a list though. I started by trying to give each module a primary focus (so graveyard for example). And while that sounds like a good idea, when you look at the final card pool, it really only does one thing well. So you really don't have a lot of deck choices with it. Everyone will just try and build the nut reanimator deck and either one guy will do it and everyone else ends up with something less ideal, or (more likely) you just wind up with a bunch of clunky graveyard decks. Part of why reanimator works for example is because not everyone tries to draft it. One or maybe two guys see it and get passed key cards and then it comes together (or not).
Now, the situation improves as your number of drafters goes up because the more modules you run the more decks are featured so to speak. But then it's back to why not just find 8 guys you can draft with and play a normal 360 cube list? I don't really have a solution for this yet (I don't know 8 people that want to cube and I'm not going to go finding them). But I'm not giving up on the modular idea. I'm going to try and make the modules slightly less focused with opposing strategies so there isn't just one clear deck to draft. Not sure how that will turn out though (it will certainly make this exercise even harder).
Sort of rambled off topic there. Par for the course for me though. I tend to do that.
