Based on speculation by the community, there has been a lot of discussion on said topic. However I find fault in how the community has priced these elixirs and henceforth I provide my own opinion on what this cost can / should be. I myself have little to gain from said elixir as I have 5 maxes, so my opinion is not biased, albeit I speed quest.
The elephant in the room... how do we treat skips for zones people own for crowns but no membership?* YOU do not allow them to skip. Owned worlds are not a factor in the price, as in my view you must be able to opt out of the elixir and back in at your discretion. But rather are walls that prevent the elixir from working at ALL. If you do not have membership, and do not own the area, you are unable to skip worlds.
Eg: I hate Celestia and I want to skip ... crustacean empire. Once I hit that zone, pressing the journal for someone who has the elixir would show *skip zone* or *skip quest*. Doing so would warp you to the next quest. For people WITHOUT membership, IF they OWN that zone then, and every zone in that world prior to it, they would be able to skip. This is to prevent obvious exploits of teleporting wizards to max lvl without membership to combat trolling and botting in pvp and pve. As a banned player just deleted their Wizard, makes a new one, and is immediately back.
Monqustia / Wallaru [guessing it will be roughly 3 days knowing novus setting up climactic duel], will be 30-35 hours. Hence 9000 crowns.
I am hoping that the above suggestions help the devs price the elixir correctly. Due note I am a fast quester, for those with membership, post your times bellow. That way a fair consensus can be reached.
