Man & Machine: The stats & more about Mobs

STATS
I am trying to keep the engine fairly simle, but I still want heros to be heroic and be individual. 

Currently the stats I am using are:

Actions: Number of actions a model gets.  As orders are given, models with a lot of actions will get moves at the end of an order phase while other models are unable to respond.
Training: Indicates target number needed for successful roll on a d6.  2+,3+,4+ and 5+ are typical and range from rabble to elite.  Most heroic models will probably be 2+ or 3+.
Prowess: How good is the model in melee.  Indicates number the base number of dice the model gets in hand to hand combat.
Accuracy: How accurate are they with a gun? Indicates the number of base dice used in ranged combat
Agility: How quick and agile are they? Indicates number of dice used when making opposed ranged combat rolls
Life: How much damage can the model take before they are killed
Skill: How many dice does a model get to attempt skill tests
Armor: How many armor dice do they get.  This stat is downgraded as a model takes damage and is denoted as 3/1.  As a model takes damage their armor will downgrade to their minimum roll.  Once at the minimum roll the damage goes to the life of the model. 
Heroism: A spendable stat.  Once a point is spent it is gone for an encouter.  These are used to simulate the luck of a hero on the field.  Spending a point will allow a model to change a singel die pool to all successes or all failures.  They can be spent at any time.  And the opponent may then spend one of their points to counteract the spent point if they choose.  This makes the dice stay as they were.

Machines have similar stats, but have no Heroism stat and no skills.  But they do have one specialized stat:  Mobility: Wheeled, tracked, Walker, Hover and Flight.  These will allow machines to traverse the battlefield quicker

Mobs are similar to the regular stat profile but have no Heroism, a training cap of 4+, no skills and armor that dosen't downgrade(for simplictity) but will end up being expensive.

MOBS
I did a little testing with mobs last night too.  Just a few combat phases with a hero vs a mob of 5.  I will have a max number of dice per roll, as a large mob could roll a huge number of dice.  We can assume there is a maximum effective number of a group, over that they get in each other's way.

Combat stats like accuracy will start with the model's base stat and add one more die per member of the mob.

I may do hand to hand the same way, but I am not sure it will be necessary simply do to the self limiting number of models that can engage in combat.

For shooting at mobs, heros will have the ability to fire at a single member, or spread their fire over a number of models.  The mobs agility in these situations will be their base agility stat +1 die per each additional model.  ie A hero fires at a mob of security officers that have an agility of 3 and a training of 4+.  The hero has an accuracy of 4 and a training of 3+.  The hero decides to fire at 3 of the mob.  The hero rolls a base roll of 4.  The mob gets a base of 3 dice + 2 more dice for the additional targets and rolls a base of 5 dice. 

If the hero scores 2 successes in the above scenario then two of the models take 1 damage, that may or may not be stopped by armor.
