My baby horde druid is now in Northrend, and having attained level 71, has her pretty epic flight form. This shot, however, is from right after she got her plain old regular flight form, at level 60, in Hellfire Peninsula, but I love this Christmas Eve shot for the gorgeous sky.
I'm no fan of HFP due to many bitter memories of quests that took hours and respawns that randomly went from taking forever to all popping at once on top of you back in the early days of BC.
But I am a huge fan of flying, especially on my druids (baby druid being my first horde druid, but my former Alliance main is a level 80 druid.) My first druid got a significant portion of levels 68-70 from flying around exploring the rest of Outlands. The only reason I didn't do the same on this one is I have been leveling her with a friend so I couldn't get ahead in XP like that. Ditto for why I have yet to do the druid swift flight form chain, which I thought was incredibly well-done, but I will go back and do it at 80.
But there is something incredibly peaceful about gliding around on druid wings. I pan around to see the sights, and enjoy the traveling to and fro. While on other characters I might still hop a flight path and AFK, even though they also have epic flight, on my druids I always want to take the me-directed route there.
She's a skinner, not an herber or a miner, so the epic speed flight won't really help her gather. But it does give her the independence to make her own path, and show off doing loop-de-loops with /mountspecial. And sometimes, it's those little things that matter, at least to me.
