Flying Mounts in Northrend

Today’s discussion is regarding flying mounts in Northrend. The opening post (OP) cited an interview with Jeff Kaplan (aka Tigole) recently discussed the Wrath of the Lich King and factors the Blizzard development team had to consider and change for the new WoW expansion.
1. They decided to open the Death Knight class to lower levels to prevent players power leveling to get level cap.
2. As for flying mounts in Northrend, according to reports, players will have to venture forth by foot until they reach level 78 at which time flying mounts will be usable.
From Blizzard’s Bornakk:
From a design standpoint, we don’t want people to just fly over continent and skip things when they are leveling up. Instead we want people to explore and experience the environment around them when they first reach the shores of Northrend. You will walk (or ride) from one quest to another as the zones unfold before you instead of just flying over it without batting an eye.
At some point though you will definitely be able to fly in Northrend. We are currently thinking around level 78, but haven’t made a final call on this yet.
It looks like they want you to actually experience the expansion and that’s not a bad thing. Without the lore and other stuff World of Warcraft might become only a grind fest.
