I would beg to differ, I would have personally placed tactical value of a force of 30 units that have already bypassed the Collective defenses mucher higher than less than one %, considering the hugely destructive weaponry the Collective employs. I'm not really too bothered by the hive fleet, its likely the planet will fall though I do intend to take a huge chunk of your force with me, and considering what will be left I doubt it would have been a worthwhile investment for the Tyranids, and given that this strain is more intelligent I can imagine it would think twice before trying again on another such world, and that's my end goal here. Essentially, re direct them.
I had this problem with the seeders, I'm glad to see the same tactics I had erected all so long ago as a contingency to their assault or the victory of Equestrian forces will finally see some use, good to know it wasn't a complete waste, maybe my overall plan for them will work the same here as well.

Hey duck, want a few 'nids coming your way? XD

Good thing I still have my Dark Energy and Hardlight weapons, muhaha. Good thing I get to show their power off too >:)
