PlaneShift is a MMORPG. Just like a card game player is considered a player in a card game, so is a role player considered a player in a role play game. So, when you say that we need a drinking skill to make players (or role players, same thing) happy, you're not being fair to the rest of us players (or role players, same thing) who don't want that silly skill. I know you were joking, I just can't let these confusions slip.
I wasn't speaking about losing levels. Just making other skills harder to level. For instance, for each point you raise in Job skills, your Combat and Magic skills need one extra advance to level. This would make characters tend towards focusing on certain areas, because if you raised too much of every area, everything would become harder. It doesn't waste any hard work, it just makes the work actually hard.
