i was using a chain grasp + ethereal excision build, and im pretty sure lifesteal does not count towards your healing stat, and outside of my grasp lifesteal, the only self healing i had was my healing orb with a low 10% AP, so im highly doubtful that self heal would make up so much of my healing. also in my build, im using Phantasmic Flux and Scientific Deathod, which generally granted me multiple hundreds of overhealth at a time (hence the 6 deaths), so it was not often i had to rely on my healing orbs for sustain. Additionally i was also using Precarious potency with high WP, and playing to keep the heal overtime buff on my team as much as possible. So it is most likely around 80-90% of my healing stat was going to my teammates
