Tiamat Set nerf ?

I mainly play as a DPS but also have a pala heal. A few days ago I decided, to reactivate her.
While doing so, I noticed, that the 5% outgoing healing Bonus from the Tiamat Set is now listed under outgoing healing.
Not long ago, it wasn´t because it was a multplicative buff. Does that mean, that it isn´t multiplicative anymore and got a big nerf?
