With the new HQM in play and the crafting time of GP halved, I think the strength of walls in different materials needs addressing, mainly the strength of the currently useless metal tier and the now (imo) underpowered armored considering its cost
Keep wood and stone the same strength, i.e. 1 and 2 C4 respectively. However, as they’re the cheapest by not requiring any further processing, consider bringing back tool raiding in these materials.
Keep tool-less raiding in the metal tier but buffed to require 2-3 C4. I.e. similar strength as stone, but you need C4.
Give the armored a large jump, say to 5 C4
This would give us something to spend our metal frags on!
This might sound like going back a step to before we had a “strong” and “weak” side of a wall, which I do like, but the “weak” side of the wall would be really weak and you can have an option to double skin a wall?
