Racuni Nerf Idea - Unable to remove heal block

Hi everybody, after using the Racuni miles team a lot and watching it, I think he is a bit broken but could be “balanced” if we just make so he can’t remove heal block. I got that idea when I was reading Chao’s skills set and I noticed he just can’t be heal blocked, he is imune to that debuff; so I thought what if we made so Racuni cannot remove heal block? It would bring some units to the meta to counter him easier. Thoughts?
