Solid floor material adds HP bonus
Solid floor material (concrete,bricks) make buildings more stable and durable. Therfore it adds bonus HP to the structure.What ?
Current usage of floor materials is limited. Its mostly used for cosmetic reasons.Concrete, and bricks might be used for reinforce defence structres, wall, turrets. Or / and basicaly any structure. Lets asume, nice solid base has positive effect for building stability and cohesion. So it takes more time to be destroyed.
There should be some progress like :
Brick floor add 5% HP
Concrete 6% HP
Reinforced Concrete 7% HP
Hazard concrete 8% HP
Reinforced hazard concrete 10% HP
Why ?
Its another option how to improve the base. More detailing.It is another reason why use floor materials.
It gives only reason why use high level floor material, other than cosmetic.
