This one, about EXP, is just stupid in my opinion. 15,000 EXP for a single stat point is basically the same as saying "it's impossible." I mean, at this point, even if you put all your qi into EXP, I don't think you'd even reach 40,000–50,000. I could be wrong, but not by too much.
Yes, exactly. That's why I said isn't certain, because besides the fact of being utterly impossible it seems that Niki was subjective(Something like he'd just "fix a problem" rather than specifically saying adding the GP of 5 or even citing EXP, he even showed the code of the cap increase rather than EXP, which leads me to think that it's more probable to not have an alteration than the opposite).
At end, in my view, it's doubtful that Niki will apply a constant GP of 5. If he even change something I'd visualise a more orthodox change like applying a new GP of 5 past 100 as more acceptable.
Some people can even bring the point that Body Refining is way more expensive than standard Cultivation, but the current system already express it completely well.
Basically, the numbers for a perfect foundation were already leaked;
To reach Golden Ocean(Perfect Cultivation foundation) you need a Dantian with 3.600 refined Qi.
To achieve II-star prismatic/Nirvana grade foundation you need one stat at Prismatic range, that's, 150+.
I'll show you the difference: To reach 3.600 of Dantian Size you just need to gather and refine 14.400 Unrefined Qi, a simple enough process. You don't think so?
To increase one single ****ing stat to 150 you need to increase the stat cap 100 times, which already translates to 25.250 Unrefined Qi. Then come the process of actually increasing the stat with EXP.
Assuming you're in heavenly where the ratio is 1 Unrefined Qi for 60 EXP, and keeping the current 3.125 EXP per stat increase, you need roughly 52 Unrefined Qi for each stat increase, which is 520 Unrefined Qi for each 10 and 5.200 Unrefined Qi added to the 25.250 that's, in the end, 30.450 Unrefined Qi to increase a single stat to 150.
(If we consider the constant GP of 5 the value goes to ~250.000.000 Unrefined Qi, so yes, not happening).
