I'd like to make a suggestion about the Wotlk expansion in general and it would be .. make the flying ghost mount available at all time everywhere.
Many times, i've encountered deaths (players, woops i jumped, underestimated a group quest etc.) and i just .. couldn't get my corpse back.
Lodged in a place too high, in a place where i got dropped by a teleport / npc and just can't walk there, the cemetery is in a crevice for WTF reasons and my corpse is around Ulduar and whatnot ..
You often spawn as a ghost and eventually when you hit another region when ghost flying is available you can finally get to fly to your corpse back. Maybe.
Maybe, because sometimes you just can't find where the F* you're supposed to go to get the fly mechanic to work and you walk for 10 minutes in the snowy mountains like an ******* trying to find the path leading to the next zone.
Then you alt-F4 and you go to the website to force a hearthstone teleport because you're stuck.
Just make it widely available EVERYWHERE in Northrend .. and just to SPAWN on it immediately instead of trying to make that stupid pigeon ectoplasm to be willing to help.
