I have seen many AI use phased shields. Of course, not in the early games - they just don't have the time to research them. I'm not positive, but I believe the AI has a much more "balanced" research regime than I do - I tend to focus on 2-3 specific areas, max it out, and move on to the next area(s).

UmberGryphon - I believe the normal mount for Enveloping Acid Globule is 100 (I too am at work and am calling it from memory).

And Raynor - I think the only purpose for Ripper Beams is a stepping stone to Wave Motion Guns. However, I see the AI building 'em all the time. Their range seems way too short for my taste - I think its only 2.

I do conceed that PPB's are a great early game weapon, but as many have said, the AI needs a little help at first to get going. Once they have about 50-60 turns without encountering a human, they become a much better challenge. That's why I don't use 'em (PPB's) and thats why I always play in a huge galaxy (250 systems).
