Generally mobs above apprentice (loving that title) take ages to spawn.
The latest change you did was good, no bugged spawns anymore. But now the mobs in the eastern desert (gendran 'clan') are way too strong (they 1-2hit my lvl20 char with 650hp...very fast) and there is no way to find any items above enchanted wristbands.
The only 'hunt-able' monsters are either the gendran apprentices or the slowpoke-spawning dudes in the southern graveyard on the first continent (which both give crappy xp).
And no predator helmets anymore. :p
