I do find the unnaturally fast rate of corpse decomposition in other games disturbing. It's not the hulking, doom-aura bosses you should be worried about, it's the super efficient, flesh liquefying microbes that are the real terror!
Yeah no one seemed to care very much about the microbes in TW2, though I wonder what kind of backlash would've appeared had CDPR made the Kayran Corpse vanish into a loot bag.
In my mind stealing even a single Nekker is just as bad. They could've at least flagged Queen Endregas, Arachas and Trolls as semi-permanent.
Anyway Flash has incorporated more persistent corpses into his combat rebalances for both Witcher 1 and 2. Since he's CDPR staff at least somebody over there cares a bit, so I have hope for TW3.
At least make it an .ini switch guys I mean really.
