Dragonflying is and will be for a long time the best addition to the game in a loooooooooong time.
Sure there are some loudmouths here on the forums. Mostly the common guys who complain about everything and for whom open "world content is overtuned" (sic)
Ingame? For previous difficult topics like sylvannas, BFA gearing and whatnot there was a constant thread of people complaining about it in the general chat.
Dragonflying is never mentioned.
You will keep flying in the old world. You won't get in the new one. I hope not even for any future zones. Old flying is a old and boring system which makes no sense.
They won't abandon old flying completly. You will always get new mounts and be able to use it in old zones.
But it really really hope they will keep DF for everything in the future. Not only because i can't stand this huge cloud of hovering dragons abover fucking rarespawn site. Looks ridicoulus. Feels stupid.
Dragonflying is easy to use and better than flying in nearly every single aspect. And flyingn is actually fun now because it is something you engage with.

Why do you talk about DF? You don't play it. One weekend is not enough to make any kind of claim about anything.
And stop talking like you have a huge amount of people with the same opinions as you. You don't.
