Occasionally whether in close or far proximity to me my Druid bot will heal the enemy with his main heal spell.
I at first thought it was just an issue where ti had no target for me and was in the middle of a heal trigger and so it used a close target but this is not the case.
I have no idea what is causing it but it has indeed wrecked me sometimes as I almost have an enemy dead and Druid heals it to 30% health.
