Armoured pen decay timer

Armoured Pens have a ludicrous decay timer for a t3 building in my opinion. 1hr 50 mins is way, way too low. I know placing foundations near it or under it will increase it but the fact remains that it’s a t3 building that decays in less than 2 hours. Needs a buff big time should be a couple days minimum. I just don’t understand the idea behind it falling apart so quickly.

to prevent 1000 of them spread out around bases for land claiming.

But sandstone foundations are way cheaper to make anyway. Why would you use pens and not just foundations of land claim soam is all your after??

Because with a t4 carpenter, it takes 1/7th the stone and 1/3 the wood to cover the same area if it is flat. quicker spam rate.
