The most "skill" that a GF requires is not blinking while staring at your enemy for 10 years so that patience / boring argument is total bs since GFs are way more boring with teams like FRA1, FRA2, TZ0
but the fact some people say duels are just about chambering and patience shows that they dont really know how duels work and didnt even try to deal with duels
And as we have seen, those teams get beaten by aggressive teams (when they exist). Such as team ENG or OG recently.
As I said, proper leadership, teamwork and good aggressive players (such as Python Ivan Bagins DOMI) are how you beat these teams.
About the duels. I'm talking about high tier duels and some people specifically. Such as Extazz and Drake. I'm not saying all duels are like this, I have played some fun quick duels before too. But those duelists will always lose to the more patient ranged + chambering playstyle of them.
Saying I have no experience in duels is ridiculous. I've indeed not taken part in many since I don't enjoy them. But I've watched finales before and this is what it generally comes down to.
Also sadly, you get forced to play duels every now and then in GFs:
