Every 3rd map has 'mobs take % reduced from crit'

As the title says - in Phrecia 2.0 pretty much every 3rd red map has that mod 'randomly' added. I guess the mod pool is not that big but it is annoying. Why some builds are left to be free with no random mods affecting them and some get the smh reduced by 40-50%?

either that or the other maps have - goatmen - skeletons - sea witches and virtually drop no loot anymore since these mob types seem to have some hidden loot penalty. the map mod system could really use some work.
