Haha, holy shit you're mad.
Danno's suggestion at its core isn't great; it's to make the core of character development impermanent and fluid. In doing so you force specialization on players, as the investment to gain stats is the same, and thus changing your direction would hamper any value you would otherwise provide. You could always make stats cheap but that's against the nature of what Danno wants and it'd also make the core of infrastructure mostly pointless. Alternatively you could rework everything else to fit the system and its reduced levels of effectiveness but that has the same cheapening effect.
When you tamper with the numbers the way that Danno and the last few people purporting that have suggested then you end up attempting to revamp the entire game to its core to permit a change that doesn't add anything to the game. I'd argue that it takes away meaning from the game but I'd be wasting my breath because just about everyone else already understands that. Character development is a thing of fun and beauty.
As for arguing that brickwalls are too powerful or not powerful enough; welcome to worlds 3-6. To enact the same degree of immunity upon palisades will garner them the same treatment. The last thing we need is a return to vaults.
