If ya already done a quest ya got a reward for it already.
EQ,LQ,Area Quest with only +dicksize, explore-exp, I'm sure you got something
out of doing it. Some players might even have learned the quest's secrets when
completing it, therefore I think it doesn't make any sense to reward anyone
for doing the same shit over again. I mean - hell, if you don't think you got
reward enough from doing it the first time - why the hell did you bother to do
itat all back then??
Say you completed a quest 8 years ago which I have not completed. Say I do it
tomorrow and get n k gold for doing it - I'd say you have feasted upon the
benefits from the quest for 8 years already and stupid me who never bothered
won't be fully compensated just because of some amount of gold was added to
the reward.
Main point: Can't reset all players whenever a change is made.
