A sith school in general doesn't make sense. Even if you had a large number of Sith operating in the open they wouldn't have one. They're not interested in spreading their philosophy. They're just interested in power and control. It makes sense for a master Sith to have an apprentice because he can't do everything, but why would he share his knowledge and power with random strangers? Further more specifically strangers who are hell bent on acquiring as much power as possible and would kill him given 1/2 a chance and anything to gain from it?
It would have been better set up as something like Sith hermets living out in the wilderness that you have to seek out and convince them to teach you. Also spread it over all the other planets and just cut Koriban out, or have Koriban as just a really small area were you find the most powerful of the Sith masters.
Of course this would have destroyed most of the more interesting stuff Bioware made.
A similar post to yours got me banned
Was ..naive?.. enough to post something similar in the SWTOR forums, when information about the shitwreck it would come to be started coming out
The sad thing is that it is a logic that expands further..how many types of RPGs have we played where 'mage' academies exist?
