We have a nice topic about buffs and debuffs, this one
Next, we have some topics with confused players of how it should work, like this one
So, my request is that someone provide a some kind of “math rules” for buffs and debuffs, you know the BODMAS stuff.
I agree it’d be nice if this was given to us by the Devs. In the meantime, I’m working on understanding how stackable buffs interact with each other 
I’ve actually already found out that DoT always goes before HoT but as you pointed out in the topic above regarding BK+shared damage, there’s more rules.
I’ll try and put a reference in that Status Effects guide.
