Influence of Upgrades are to big?

[Vomitus]

So this can be a question of:
"Should (existing) factories and upgrades must increase bounty?"

Factories - yes. Bounty increase provided by factory must be affected by upgrades.
Upgrades - yes, but not explicitly.
Each upgrade must increase bounty provided by factory owner.
Let's make some approximate proposals:
Force upgrades will affect factory bounty by X per upgrade.
Teammate upgrades will affect factory bounty by Y = X*4 per upgrade.
Your upgrades will affect factory bounty by Z = Y*2 per upgrade.

This would make additional upgrades to influence much more on a factory owner than Force upgrades. Multiplier 4x was taken because each 5 mins force grades both armor and weapon.
And if you who owns a factory want to buy some upgrades you will receive significant increase in your bounty.
The X must be found such that when both upgrades = 0 Player's bounty for owning factory will increase for same amount of gold that it would if he had a weapon for same price as Factory costs(3500). When both upgrades = 30, this bounty for 1 factory would be three times of a bounty with both upgrades = 0(i.e. same bounty as for owning 10500 gold weapon).
Between 0 and 60 upgrades(30A + 30W) bounty should be distributed linearly.

Now, if someone makes huge amount of upgrades(let us say, 20), his teammate bounty for factory will increase to ((60 - 20) + 20*4) / 60 * 100% = 200%. So when your teammate makes 20 upgrades your factory bounty will be two times more than it would be. (Actually, this percentage changes from 200% to 400% according to amount of total upgrades done)
For a person that makes upgrades bounty for owning factory will increase to ((60 - 20) + 20*8) / 60 * 100% = 333%. (This value also changes according to total number of upgrades - from 333%(when max) to 800%(when 0 upgrades made by force)).

Sorry, have no time for now to make some examples:)
I'll be back later and provide your with good examples if they still be needed.
