Lucky things like a power 3 flame 1 bow can be game changing.

Or maybe a flag for regions which allow fishing, could be an interesting last resort if you are really far behind. Having the flag would make it optional for map makers.

I like that idea @TomShar or maybe make a XML module to turn fishing/mob drops off.

There is also fishing now which can be overpowered. You can get things like a PowerIV bow.
