Blood Elf char in WoW? Looks like a DK to me
Mine is a NE (Night Elf) DK.
Anyway, take a look at tunaisafish's
Enthusiasm Tweaks. The project is, as far as I'm concerned, complete with different options to tweak how you want enthusiasm to work for you in Sims 2.
I use tunaisafish's enthusiasm-based mods with no issues and would recommend it to people looking to control enthusiasm and messages in their games for their Sims.
Let me know if this is what you want.
