lol u guys u didnt lose any %(exp) the amount needed to reach next lvl went up so ur 650kk w/e u farmed is still 650kk only now u need more exp to lvl up hence ur % went down not the exp u had pretty basic stuff...
mistake ur making is comparing % of the old exp needed 10% isnt 10% anymore its not the same value that it had
since im bored enouf il type it out
76-77 old guy farmed 1000 exp(100%) our friend rip farmed 10%(or 100exp)
now the new value for 76-77 is 2000 exp(100%) now suddenly 1000 exp became 50% (help i lost 50%) but rip only farmed 100 exp wich is now 5%
doesnt get more simple then that ;p
