I usually do pretty well in duel, and I don't have any looms. I'm sure there are a ton of players in the same boat.
I wouldn't say tons, but there are a few others on NA I think.
Those two blackrose guys at the top there are pro native duelists with no heirlooms like you, right? Because when they get serious, they start pulling off what looks like macrofeints except executed manually in the same way that you do.
What I find more amusing is that not a single person at the top of the rankings on the NA side is a dedicated 1h player. In fact, the only ones who I've seen using 1hs with any kind of frequency at all are you, Luk, and (at least recently) Rohypnol. Everyone else on the list there is either 2h or pole.
