Tier I - zombies are ok, Lv5, not that much damage. Wide open, easy to avoid them. tier II- Spiders are ok, but a new player would avoid it tier III - Better change it, because snow golems can see you miles aways slimes and too much of them I cant camp at a tree with snow golems and slimes (creepers) keeps tackling me while I do woodcutting. tier IV - Cave spiders poison you too much, so nerf it tier V - moderate mobs sometimes 3 hits a cube dies.
