mustardoverlordis actually does matter if the base value is good or bad, because whether you reduce the radius of the iron bomber or increase the radius of stock pipes is a MASSIVE difference, and part of why I've been defending the iron bomber is that I don't like the idea of the direct radius being lowered in the first place, which I'm gonna say more about in a giant wall of text that I was writing before I read this post.
I mean within the context of changing/keeping ONLY the Iron Bomber being our sole balancing tool, which is what I understood #92 to be saying. Being that if we think Demoman needs a nerf, nerf the Iron Bomber, if we think Demoman is fine, keep the IB how it is.
But the balance is much more complicated than that. I see this more of a discussion about GL balance as whole, rather than just about the Iron Bomber. At this rate, Demoman is going to become an IB only class, so talking about the IB in vacuum vs the other grenades is not useful. I think the two valid sides to this discussion are either you think what the IB has in radius is good for the game, and should be applied to the other GLs, because it makes no sense to force everyone to pick a single GL when there would be some valid choices all other things held equal. Or you can think the IB radius is bad for the game, and in that case, it should be the same as stock.
I don't think there is a valid argument for keeping them different, but hopefully recontextualizing the debate into two sections: should they be different, and then if not, should we use the stock or IB hitbox, will produce better discussion.
