By this i mean you factor in the current state of the story and teh races.
for example, if you're a Cenarion druid, you don't attack opposite faction Cenarion druids ( Zandalari and Kul'tiran drust are exempt)
You don't attack other death knights unless attacked (if yu're a DK)
if you're a Void elf for e.g. you don't attack blood elves. (vice versa happens)
If you're nightborne you don't attack Night elves (but vice versa happens)
Things like that.
