Yes, which is when he was revealed to be a fraud, a notion believed by 99% of the OP fandom lmao, you can't have it both ways — you can't hype Xebec for beating Garling and revealing GV Garling to be a bum, and in the same vein hype Xebec for beating GV Garling, as if GV Garling has any remotely impressive feat or even the slightest lick of ACoC.
Your argument is contradictory lol do you believe that Garling was a top-tier on GV, yes or no? If yes, I have no idea why and you're on your own with that one. If no, then I don't get your point — minus regen, GV Garling is obviously weaker than DR Dorry and Brogy combined and arguably weaker than them individually. DR Dorry and Brogy couldn't hit Zoro with much stronger backup.
