cats:
i dig the tappedout multiple methods of categorization. they're all important to me (yep, even 'latest set')
sure like you never have delver tidespout.dec or nacatl primus.dec and that's ok! but ugh can you guys imagine what happens when a color has no cohesive identity, and there's not enough fixing, so you can't mix and match and all options just suck? like the guy who was caterwauling about how it was impossible to fix his black when every deck would be carnophage g'brand.dec was pretty hilarious -- his orzhov section may have been laughable but the cube gestalt was also worth a derisive chuckle
as for kird ape and friends, i see little value in strict color balancing, but accurate (if not precise) bookkeeping has been necessary to keep 7/9 decks from being green/x/x every wednesday. i dunno what the problem with the monkey is, it's a gruul card = .5 G / .5 R or so (there's a thread on the old google discussion group about this) -- like you're never playing kird ape without G or lingering souls without B, so ... anyway i think with big multicolor sections it's impractical to balance precisely, given the nature of its good cards (best as 4-ofs in constructed) red should lean the heaviest on gold/hybrid and blue should have the least
