Angry Mob, an LotFP class

The Angry Mob

So I loved this Extras class for B/X and wanted to do my own take for LotFp. Fair warning, this thing is unplaytested and probably not too balanced. It was intended as a joke class, but I put too much energy into its creation not to post it.

• You are literally an angry mob of unleveled peons. You are pissed off peasants, fuming farmers and fishermen, commoners catalyzed into action by the unfair cruelty of the world surrounding you, and your desire to mete out justice, or at least to earn enough coin to assuage your malcontent.
• Level and save as a dwarf
• 1st level HD 6, minimum of 4
• Each hit point represents an individual member of your angry mob. 
• You cannot regain hp by resting or by healing spells. Mobs only regain hp by entering a town and inciting other peasants into joining up. Rescuing prisoners/slaves/hostages may also be used to rejuvenate hp.
• 4-in-6 chance of Open Door. You have a lot of bodies to throw at it. If your hp drops below 4, your Open Door chance drops to match it. So an Angry Mob with 2 hp now has a 2-in-6 chance.
• With a minimum of 4 people attacking an enemy, someone is bound to land a hit. Attack Bonus is your Strength modifier + 1d4
• You are, however, just a bunch of angry peasants adventuring in the clothes on their backs and fighting with farm implements. You are unable to equip armor and default to the base Armor Class of 12. You also can't equip weapons, and deal 1d4 worth of damage per hit.
• At level 3, its assumed your Angry Mob have managed to scrounge up a hodge podge of equipment in the course of their adventures. This guy found a helmet, and that lady found a cracked, but servicable shield. Someone got their hands on a sword or spear. Your AC is now 14, and you deal damage as 1d6
• At level 5, one member of your mob has gained enough experience as an adventurer to take a class, fighter, magic-user, or cleric. If you choose a caster class, you may cast at half your Angry Mob's level rounding up. If you choose fighter, you get AC 16 and deal damage as 1d8.
• At level 7, another member of your Mob may take a class. Choosing the same class results in doubling your spell slots for casters, and increasing your Attack Bonus for fighter by 1.
• Classed members of your mob are assumed always to be the last to die. If you are reduced to 1 hp and have at least one classed character and survive the encounter that led to your Mob's decimation, you may choose to turn this classed member into an individual character at half your Angry Mob's level, rounding up. This applies to as many classed members as you have hp left. So two classed members,  2 hp left, you may make 2 individual characters. From then on, these characters are no longer members of an Angry Mob and level normally as their class.
