The idea is that min-maxing would do just that, and leave you with one massive strength, but glaring weaknesses otherwise (not ranking up attack speed makes your combo extremely hard to land, not ranking up AD makes your overall damage a lot weaker, not ranking up movement speed makes it a lot more difficult to reach enemies in the first place).

I also think 10 seconds to 100 - 0 someone is perfectly acceptable, and might in fact be too slow relative to the DPS of other champions. I think Bak Mei would be able to kill enemies faster than that, and considering the limitations of his kit, that would be absolutely fine.
