I don't know percents or time-periods of how monster exp-worth are tuned.
But it's kind of depressing when monster is 1/4 of it's usual exp even if you
haven't visited the place over a week.
In partying it's problematic when different members have different tunes on
different monsters and every monster might end up being shitty exp. Should
leader first ask from member that when they have killed these and these
monsters?
Could it be better that only leader's personal exp tune affects when killing
monsters? Would make leading more fun and also would suit to nowadays insane
exp-needs.
