“Flying mounts are bad” is something we tell poor people who couldnt afford them …
Flying is to this day one of the best things added into wow …
When flying was added into TBC it instantly opened whole world (well outland, but theres nothing to do on max lvl in old world anyway, which is another issue on its own)
Traveling at your own pace, going wherever you want, no mandatory trains and bugged boats, players could be everywhere at once …
You need help ? Anyone can just hop on mount and be with you in few moments.
Everyone is trashtalking RDF for porting you right into dungeon, while I am sitting here, waiting for them to remove stupid meeting stones so everyone has to actually move …
And as PvP main, absolutely fantastic, so much mobility, chasing down gankers, helping your people who are getting ganked.
Good luck starting fight somewhere when people need to spend 15 minutes and 2 boat rides to get to you.
Our guild was one of the first who got Alar on our realm, when someone called out in guild they got ganked, phoenix flying overhead and full glad rogue disappearing midair was last thing many horde players saw …
We once held started absolute slaughter in barrier hills, you would see both horde and alliance players sitting on their faction terraces aldor/scryers eating up and buffing, then taking off and fighting around the ogres, this went for like 2-3 hours, and it was pretty fun since there would be only max lvl players, no undergeared lvl 60 getting caught in crossfire …
No stuff like that would be possible without flying mounts, the only reason why WPvP was active in vanilla is because it sucks and there was nothing else to do.
With outland and/or northrend allowing max lvl players to be basically anywhere, you would never run into anyone with stupid boats and slow ground mounts …
What was bad about flying is, PvE scrubs getting 310% mount for free, druids getting free flying mount that has instant mountup and can harvest herbs without dismount … and later when blizz abandoned flying, not caring about unique zones for flying, adding stupid prequests and timegating and creating boring garbage designed zones that arent even fun to explore …
