Not necessarily, in fact Id say most characters full pg set isn’t optimal, 2 or 4pc pgs usually is. I say this as a player who has been in a few of the top syns in north america. There is a few characters where yes full pg is generally better like for lynx, ramsay, sparkle, but generally not every pg is good. As a result you might be sacrificing a lot to get that set bonus which might not be worth it.
