Add some crafting too
make it more interesting.
Old golden gun you can get in one hour. Do not repeat this scenario. And we do not need exact numbers of duels fort battles or adventures. Make it for example take 50 000 xp from fort battle 20 000 xp from duels and maybe 5000 veteran points. whatever.
now hte quest about the old golden gun is known..... it's easy.
in those days it wasn't that easy when nobody knew anything about the questline.
so you can't even compare it.
the biggest problem nowadays is not so much the questlines.... but the fanpages like calc.net and the wiki's that post all the questlines right away on it.
I myself aleady noticed that nobody even read the mission messages and just keep asking for the answers or a link to the questline.
While the answer is plain simple in the mission message? Most of the time it even is in it specifically.
so an easy or a hard quest? doesn't even matter... players will complain anyways... and instead of searching themselves, keep asking the same questions day after day.
