You're not wrong about the farming Doors for QP usually being more efficient. A bare-minimum run of 40AP Doors with no Mona Lisa CE is about 850k QP. This means every single door drops a silver chest. One MLB Mona Lisa (which anybody can have access to via support) is +10%, so +~85k which makes for about 935k QP. If you get at least one gold drop, this amount breaches the 1million QP mark for the run, so it becomes ~40AP/~1mil QP. Most of the time, this ends up being better than farming events, though some events like the Fate/Accel Zero event had/will have extremely good currency drop rates for currency->QP exchange

Tl;dr, if you have nothing to do with your AP, just farm QP from 40AP Doors, making sure to always take a support with MLB Mona Lisa. Having your own Mona Lisa really helps but even if you don't have one as long as you take a support with it you're fine
