I'd have said that Zoning Board is different from the others. There's a lot more variety possible in minion cards for all sorts of reasons - they're generally easier to play, if you have certain disciplines (or clans etc.) you're pushed towards playing some different cards anyway, a weaker card may well stack easily with a stronger card so it's still potentially worth playing a reasonable number of both both (e.g. an okay stealth card and a good stealth card), a little variety might be good if Direct Intervention is super popular etc.
With master cards, you're really competing against (say) the top 20-30 generally available master cards, and the few that are good for your specific clan, sect, or trait, and you only play one proper master card a turn. A few might become reasonably competitive by switching them to a trifle. A few might become reasonably competitive by dropping the price. But a bunch are just really fiddly and really situational - even if a hypothetical somewhat okay master card becomes a trifle, it's still competing against Villein, Wash, maybe Wider View and Vessel - all of which are really good, and playable practically all the time. Many of the best master cards can be played at almost any point in games (e.g. Villein, Giant's Blood, Dreams of the Sphinx, most hand cyclers, Ventrue HQ, DI, Wash, Fame in a rush deck, intercept locations with walls, Ashur). The ones that are much more specific time wise (e.g. Week of Nightmares, Zillah's Valley, Frontal Assault, Legendary Vampire) or somewhat more situational (e.g. Anarch Troublemaker, Erciyes Fragment) tends to have really, really nice upsides. If a master card is pretty middle of the road in its effect and over-costed in terms of pool/master phase actions, simple fixes are going to make it really, really hard to compete with the likes of Villein or Pentex Subversion.
