Note I am not against changing the skill. I completely get the issues with the "double" NS in its current form.
However, the problem with this isnt just communication. You likely have your own HoTs on not to mention from other HoT classes like RK. They take time to go off and this skill has a very short window AND you have to basically die. Make it higher like 15/20% would be better since its on such a short window. Though even that is not perfect. For our own healing (as well as like RK) if we let the HoTs drop off it takes a while to get them built back up. We cant just go insta stop and more importantly insta start healing again. This only protects once so if we cant get the healing built back up fast enough (assuming we/healer let it drop so we can get below 5%) then we are toast.
Or like i said just make it a bubble that is X% of health or time runs out. As bland as that is I still prefer it to this version of NS.
