OOO wants to limit the use of alts, and by doing so is adding a few unfavorable new mechanics.
Why not just remove that mist tanks are separate between P2p and F2p accounts on a single computer? If the system works how I think it does (when I tried to alt drag once before my main was P2p, I think it consumed double the mist on both accounts o.e), alt dragging would not be profitable anymore, and you would not be able to rage craft on an alt and do missions on mist alone.
Because people can have totally separate sk instances. Hence the term multi boxing. This makes it so alts aren't connected at all.
