Wortox Soul Decoy II

[Koomin]

Soul decoy II currently doesn't have any real gameplay impacts that I can find.  It makes the decoy last a bit longer if unharmed, which isn't relevant in any of the use cases of the decoy since it dies when attacked.  
If the decoy gets aggro, it gets hit and dies and lasting longer doesn't do anything.  If it fails to get aggro, it lasting longer doesn't do anything since it is having no impact in the first place.  
There seems to be no actual benefit to having this skill, besides as a stepping stone for soul decoy II (stepping stone skills are a fine thing to have, just seems like they should not be entirely useless).
Has anyone found a situation where soul decoy II is beneficial that I am missing?  

As for improvements if it really is not useful (bunch of random ideas)-  
-Making it also last longer durabilitywise by taking 2 hits instead of 1 (might be a bit too strong against bosses though)
-Improving it's aggro range/taunting capabilities
-Reappearing a few seconds later again in the same spot after being destroyed
-Having a small chance to leave a soul when destroyed (more souls + soul pierce fun)

i could imagine this being balanced out against bosses by having bosses be able to oneshot it, but not regular mobs. that way itd still have a meaningful impact on most mobs, but not completely broken for the big guys?

You could maybe use it to try to lock stuff in pens. That's all I can think of.
