Because quick as a mechanic has already served to be irrelevant making it so DW is less incentivised to create a much more appealing F2P quick support. The more DW produces accessible ways to generate passive stargen the less likely quick will be supported. We will still be getting quick servants with their own selfish/party quick buffs but they’ll ultimately become Buster-Arts Hybrids for that’s what Skadi did. Made it so that quick cards are tolerable to use for combat but not for its intended mechanic of generating stars. Hence why Skadi gives a quick only 100% crit dmg buff to give us a reason to use quick cards.
The first nail on the quick cards coffin was the introduction of 2030, then more passive stargen CEs, then skills, non-quick NPs generating stars, The free Waver ticket next yearand so on. So yeah, less gameplay incentive overall.
But who knows, maybe DW would one day give us a bronze 1-turn quick buffer for completionist’s sake.
