Fair point. Counter proposal, make Glue Arrow immobilize the target (overwhelm the target with glue to the point they can no longer move), while also dropping a glue patch at the target's location (excess glue that runs off the immobilized target), affecting nearby foes.
This would add more proc options, but also it could allow for reinventing Entangling Arrow as I personally am not a fan that it is a rope that does -resistance. I rather cottage burn Entangling Arrow into something else (now that Immobilize is moved to Glue Arrow, no loss in capability). I suggest replacing Entangling Arrow with Weakening Arrow, a power that acts similar to Weaken Resolve, doing Defense, ToHit and Resistance debuffs.
