i know, but, the basic gist of packing is you have a small loader that unpacks the PE in memory right? because you can't run encrypted stuff in memory because in memory you need to run actual instructions unless it's a virtual machine that's running some custom bytecode

you have many little encrypted parts in wow. some also get overwritten with trash code before reaching the actual entry point of the game. Any changes u do on the unpacked dump will also result in triggering some integrity checks etc.

Due to the crc/integrity checks being initialized while unpacking all of those are also still fine and working properly with the re encryption
