Since the last change, shield neutralizers don't seem to be terribly bad at all. Running STFs the other day I found I could stay ahead of shield neutralizers. There's still a lot of shield damage going on in there, more than I can stay ahead of in my escort if I'm getting focused too much, but it's a far cry from running around with no shields praying that each torpedo I see isn't coming at me.
They reduced the number of shield neutralizers being fired off by the borg during STFs, or at least in the normal versions. Spheres and Gates still use tachyon beams like crazy though.
