Oh no, if they collapse then it's a simple matter of shield failure, and they can either reroute them to cover their weak spots, or they fail entirely. Which would be brilliant! We could only hope for something like that, through whatever means.
I'd like to spit in their eyes actually, but I don't think I can manage it. You've made an excellent point that the eye's a weak spot and it's near...does the thing have a brain? It's near it's brain (we hope). You're right it would be best to hinder it there, if the explodey wouldn't do the trick elsewhere instead!
