I agree, the balance is all over the place. The size effects are far too great and should be halved. There are too many humanoids that wield overpowered weapons (the "great" variety) that can kill even trolls very quickly, but are rarely dropped. "Great" weapons are something that should only appear on later levels. HP values are very inflated compared to ADOM; all player characters have lots of HP, but also receive lots of damage. PV however stays at ADOM levels, and thus it is very difficult to find enough PV. Items should grant something like douple of the PV that they currently do.
