Cuz it now requires 3 slots to create a stack of insulated wood in the already cramped space of a Carpenter’s Bench…
This requires a disproportionate amount of micromanagement compared to other crafting stations.
Might I suggest the implementation of an improved carpenter bench?
If the reason there is no Improved Carpenter’s bench is to make insulated wood act as a throttle towards repairs in a war of attrition in PvP, then …well… frak. Thx again PvP.
