Well, my frequently proposed solution to this problem is quite
simple. Reduce the effectiveness of STUDY without a teacher by a
factor of three or four, while keeping the STUDY times with a teacher
constant (or even slightly decreasing them). Then STUDY without a
teacher would represent real research into a subject which you should
be able to do anywhere without anybodys help. After all if you have a
piece of paper and a pen, why can't you do some work on the basis of
Quantum Magodynamics if you are alone in the Wasteland of Resh ? On
the other hand it should be much harder to make something up than to
learn it from a teacher.
As a slight compensation most guild towers should be given one NPC
full time teacher each at levels 4-8.
BTW, Rich, guilds and guild towers are completely without any in-game
significance now, are they ?
