Why does your OWN heroes dispel work against your own heroes buffs?

Attention Wilbur users

Those of you who play Wilbur on offense along with some high damage dealing heroes, make sure you don’t use any heroes that dispel buffs from enemies (Domitia, Panther, Evelyn, Zeline). The shared damage granted to your enemies by Wilbur is considered a buff (rightly so), so when you fire one of the above mentioned heroes AFTER you trigger Wilbur’s skill, the sharing buff disappears. MIND THAT!
