IMHO, this is just following the cheap TV serial method of dealing with powerful villians. Some 'Si Wai Gao Ren' teaches the main char some skills over night and the hero gets super souped up.
If every player does this, its just a case of everybody chest thumping and flexing in front of the mirror. I could come up with a character in 10 secs with TVB style 6MSJ laser beams and Shi Po Tian + Xu Zhu style inner power and is so super he mastered Sword 16 and Dragon Elephant Prana level 15 and Qian Kun Da Nuo Yi level 9 but c'mon, its cheap!
Its more fun to have characters with half a bucket of skills band together and use more novel ideas to deal with the powerful baddy.
