Is it new players leaving in droves or players done with the end game treadmill ?

My opinion on a jumping potion depends entirely on the details about how they work that we(I) don't know. If it worked like an super-EXP-Bonus buff, rewarded after certain initial MSQ quests that let you jump directly over the hours MSQ fetch quests straight to the next instance quest (complete Sastasha, defeat Ifrit in the Bowl of Embers, etc), then I'm all for it. Does it do more, do less? Don't really know what to expect.
