Why the delay in MSQ jump potions?

[Fatch38]

if they aren't interested in MSQ : 9 days and 10 hours, it's the time it took me from the start to the latest patch (all battle content unlocked and done except bozja and eureka) on my "speedrun" alt. which means you can clearly go faster by ignoring side content not tied to msq until you reach 90. and like someone said by doing the free trial you can play for free for most of that "time" (ShB and EW take like 40 hours if you skip cutscenes)
