Happiness should be tied with a morale system.

[Albert speer 41]

Yes you heard me happiness should have another Role it should work as a morale system which if it's high your troops are better in fighting and defending.

This should also give the small possibility of being outnumbered like 2 to 1 for example.

The enemy has twice as much troops but with low morale let's say 10k troops with 25% happiness/morale.

You on the other hand have 5k with 95% high morale,this should give you a boost on defence depending on morale for example:

25%(low morale) -25 attack bonus and defence.

50 %(moderate morale level) 25+ attack and defence bonus and a small chance of winning despite being outnumbered 2 to 1 (not more)

 

100%(highest level of morale)

Attack and defence bonus of 50+

Less movement points will be used when moving high morale troops.

High chance of winning despite being outnumbered 2 to 1 or even 3 to 1 (no more as that would be op)

What do you guys think?

Let me know if you like my idea whether you disagree,or have a better one.

Peace.
