Garling was not his prime. He's in his thirties and reached his primes 4 or 5 years later.
He got so much stronger in these years that he would go from neg diffed in a 1v1 vs Rocks to a solid low diff.
You guys need to stop looking for excuses lol, Garling should either be in his prime or close to it, he's just not the type of guy who can fight Xebec.
You have to be at the top for that.
