Mob health regeneration

[pauluzz]

Hey,

this is the situation:
Im grinding my lvl 13 conj, I attack a mob lvl 13.
when the mob is like half dead i run away,, after all the mob runs back to its
spawn position. but while doing that it regenerates its health with like 25% per seccond...
I had this a few times now and its realy annoying :/
i know there was an update recently wich had these regenerations in it but
is this normal? that fast regeneration?

Regards,
