Honestly I'm much more in favor of the Cinematic\story part of the game, so I tend to lean towards the dreaded realism. Here's a foundation.
1. It takes thought to control anything. And Real estate is controlled using men on the ground.
2. A man looking down the barrel of a cannon on a Tank Cannot be claim to be in control of a whole lot.
3. An Immobilized vehicle, with out dismounted infantry support is a liability, and is only concerned with it's own survival.
4. A mobile Vehicle with weapons is more than capable of making life extremely unpleasant for things around it.
5. All men are not created equal. 10 men are not going to be bothered by 2. However 10 would be concerned and upset by 5. Similarly a greater Daemon would hardly be upset by 5 space marines, but would be concerned by 5 spacemarine terminators (10 models in size) backed up by a fully functioning land raider.
Ok. So a rules proposal.
Objective claiming
To claim the majority of the unit\creatiures base must be within 6 inches of the objective
Only models with a leadership value can claim objectives.
I'd like to make it so that they must be dismounted or in dedicated transports.
Contesting:
Basically Anything except Flyers (in flight mode), Immobilized vehicles or vehicles with no weapons is eligible to contest objectives.
Then we look to Ricks scoring. (though I've modified it slightly)
1 point - Non Monsterous Creatures (gaunts, guardsmen, sternguard, terminators, etc.)
10 Points - Monsterous Creatures, Non Structure Point Vehicles, Flyers (Daemon Princes, Rhinos, Arvus Lighter)
20 Points - Gargantuan Creatures and Structure Point Vehicles/Walkers (Baneblade, Stompa) <500Points in value
25 Points - Gargantuan Creatures and Structure Point Vehicles/Walkers (Titan, Angrath) >500points in value
In order to contest you must:
Have at least 25% of the points of the "Controlling force"
So Angrath could be contested by a squad of 6 guardsman, his attention is distracted by this annoyance, and he will claim blood.
on the flip side, 100 Guardmen cannot claim an objective with Angrath standing on top of it, he's far too distracting.
It's a thought. I thinks it's relatively clear, and meets the spirit of what we're trying to do.
Cheers,
Alan
