But broken loose is actually right on this. It's extremely commonly known and seen that pbgc Gregor still loses in tons of cases if you ever see good filia players in casuals or streams.
Just the other day, a filia pbgc'd at Max clp range against my Eliza as I was using SHPx2 In a block string for fun, and Gregor got completely stuffed by one of the hits. And this is far from the only time this has happened in actual matches AS pbgc and not just mashing as you seem to imply that's what we do instead of pbgcing.
That's not to say Gregor is worthless for reversals out pressure, resets, or pbgc entirely. But of all the "mashable" things in SG, which I guess what this thread is about?, Gregor is fairly mild.
It's pretty rude to say that broken loose is somehow the one talking on hypotheticals and that you're the "realist" here, given that broken loose was the one here who traveled out to the latest SG major, NEC, where I saw no less than 2-3 instances of Gregor loosing as pbgc from the several filia players there, and you didn't. That's not a slam against you for not attending an American event, since obv that's a Monumental task for non Americans, but your comment comes across as insular and hostile (which broken loose started off here as too, but this whole thread is pretty jokey).
There's a reason that "Gregor sucks" is a small-meme that we say occasionally, and it's not because we haven't discovered how to Use PBGC defensively in its various uses and options either.
