I do know what good players use. Just because I'm not top tier, doesn't mean I don't watch or know a lot of top tier players. I have 5 friends ranked in the top 100 elo for trials atm. Nightstalker, nightstalker, bladedancer, sunsinger and defender(yes really) are their mains. Every top streamer I've seen or played against runs blade dancer or ns (if they're on hunters, sunsinger if not, rarely see then run titans). I'm not doubting your abilities to get kills with gg, a good player will get kills with anything. But ns and bd have more "tricks in their bag," they're just more difficult to master and use effectively.
