Doesn't it seem ridiculous that you can earn as much CR per CE by crafting than dungeoning? I can craft two 2 star items per day, safely selling each at ~4K profit. Then every fourth or fifth day, I'll land a UV which sells for significantly more. I'll take a guess and say each of these average an additional ~10K profit. Doing the math, that's 10K CR / day by crafting.
Other than possibly the current T2 Emerald Falcon gate, where else can you earn that kind of cash? Is the only reason (outside of fun) to run a dungeon, to collect materials for additional crafting?
What 2 star item are you selling for more than 4k each? Also this only applies to mist, doing dungeons can still net you a profit even when using CE, not to mention the materials and heat you gain.
