Please give us an option to disable this mythical machine. This "upgrade" makes many other abilities that deal with mobs worse. In general, the normal mob is the least valuable, so making it show up multiple times is a downgrade.
For example:
- Snowball + Reload may waste the extra shots on the armored mobs.
- Heart Pickaxe ability spawns normal mobs and the ones with armor prevent you from clicking on many of the other mobs.
