If you target moves or starts doing anything else instead of casting, the buff gets less effective each second; that is true for both SCH and AST. However, the Arrow, even though it has an obvious RNG component, is concentrated and can be stored to be used in an optimal situation. Depending on the situation and if used properly, you can get more DPS output from it by using it on a single target than Selene will be able to get from an entire party. According to my testing in a dummy, Selene barely added 25-30 extra DPS output to a DRG, which is supposedly one of the best jobs to receive it; and that was in a dummy situation, with no moving and no mechanics.
Even with the capacity to spread that card, AST is still statistically less likely to provide an equal or better dps boost over the course of the fight. Of course it's not impossible, just not guaranteed. That's what's being gotten at. Reliability and predictability are simply valued more.
