XP gain from fishing should be turned off.
Its way to easy to make macro/bots that will exploit it.
I know its going to be hard to prevent macroing but fishing is way to easy to exploit.
And Devs you should not be afraid to make rollbacks - of course first you should try to fix it without it but you should use that tool if necessary.
not fixed bugs or exploits will ruin game like DFO :/
