As always, thanks for continuing patches. Sounds like the rollback to the old shield mechanics makes sense, but I must've missed the conversation about having the HFFs take "radius damage". I was really enjoying their fixed size; I thought that added a deeper variety of placement options (with shrinking FFs, it pretty much always makes sense to lump squish everything as close to the gen as possible), and also felt that added a needed differentiation between the HFFs and regular ol' FFs above and beyond the armor thing which I feel is a much smaller difference.
I hadn't noticed a problem with them being destroyed more often. And if they are, so what? That's the price you're paying for a superior shield.
