How formidable would YTS or GST be if infused with Greats-level inner power?

[tape]

So if Yang / Guo got 3 XYP elders' IEs, they should achieve mightier greatness than XZ!

Based on Yang Guo and Guo Jing, I'd imagine they have some good genes for martial arts so I'd take them over a whole ton of characters based on genetic potential alone.

From fights of weaker characters though like in SPW, where even weak fighters of weak sects can slaughter somewhat renowned fighters, I think any disciple of a major sect with a few years of experience should be better than any freelance fighter.
