I am checking quild system at the moment.
So be prepared to possible changeds.
Current changes: 
Amber lost druid guildmaster. Humans are now to find other master.
Half orc caves lost their seer, seek diviners in other areas.
Some guildmaster got flags changes. Now if you attack master, 
you will be punished(may be).
Next possible changes:
I've analysed only half of masters, so there can be more changes.
I'll check class practicing system. Players who practice opposite class
spells and skills will get some restrictions.
At the moment only class is controlling in balancing.
I will add specification dependence too. 
Worst regards... Ger
