Whenever you create a new char and go through the mini tutorial, you're given some starter pack containing various potions/consummables to help with the leveling process.
Except, well, the whole package is incredibly heavy, so people rarely use it (that and the leveling speed most likely).
Said consummables have no selling value (obviously) and are account bound, so they have no use aside from being consummed or thrashed.
I propose a (massive?) reduction on those items' weight to make them more usable.
