I think there's a way to leverage virtues and flaws and make character creation potentially easier. I've shared (elsewhere) my view on a directed character creation that takes you through stages of the character's background (childhood, what it is that gives them their magic, their apprenticeship, their House/tradition, etc.) and at each point the decisions you make open up a couple of V/F choices.
Quick example... If I decide my magus' magic comes from some kind of frost giant lineage from back in the day, that background might open up a focus in "cold effects", or you have some kind of affinity with the creatures of the arctic north.
Rather than leave the player to scan through pages of virtues and flaws deciding whether the character's magic comes from the blood of a frost giant, a curse laid upon their family, a bargain made with a faerie, a prophecy foretold, or some other kind of background, directs the player towards certain specific options.
These "backgrounds" for want of a better word (and I appreciate that this is probably now overloaded what with D&D5 having backgrounds too) could be setting and tradition specific. Once you start layering them up (you're from a poor background / you were abandoned at a monastery, your magic is a curse / a spirit gave you its power, you were saved by your master / you were stolen away by your master, etc.) then your character starts to take on a life of its own and the choices of V/F (or equivalent) start to arise as a natural consequence.
Those descriptive elements also start to act as story flaws in that they give the storyguide something to hang a story off.
I could also see each supplement (based on area, time period, magical tradition, whatever) publishing new "backgrounds" that support the supplement and the target play style. So if we put out a fifteenth-century supplement, the action might move to the Italian peninsular and we might have backgrounds modelling artistic patrons, alchemists, mercantile families, etc. These would be different from the Celtic/Pictish/British/Druidic backgrounds that the sixth-century British Isles setting provided.
I don't know, it's an idea, right? I like how Virtues and Flaws allow me to make my Verditius a little different to your Verditius, but I don't like being swamped with a lot of Virtues and Flaws that I don't really want and being left to choose between them. I want to build my character and for those special touches to derive naturally from the background choices I make when building the character.
