If the Child deals area damage in PvP, so should Tether.
Tether is a super, with subpar tracking that makes you go slow, and only kills with multiple direct hits from a volley.
Meanwhile, Child of the Old God flies directly to your enemy no matter where they are, from seemingly any distance, around corners, and continually damages within its large radius….. and it’s tied to a class ability.
This is horrifically unbalanced.
