A few weeks ago I came back to WoW after a couple years away. At the time I talked on a couple threads here asking what was different. While the answers were helpful, they dealt mostly with changes to the classes and to BGs (which I avoid like the plague).
So for those of you returning (or new) here are some things I discovered over the past few weeks. Many of them I found out today while doing some unintentional corpse runs through areas I thought were safe, while I was trying to get the Hallows End treats.

You now get loads of new flight paths right from the start. If it's not my imagination, you get more as you level too. (Use them folks! I gained a few levels just with the xp from touching down at flight paths!)
Almost all profession trainers are in the first town you get to once you've left your race's initial starting area. There's no need to run to a major city. (In the case of Dolanar, the skinning trainer is no longer way outside of town, and they even teach mining - though there aren't any mining nodes till you hit Darkshore.)
However if you want to get to the major city, every "secondary starting area" has a flight master.
You can level fishing anywhere. You no longer have to be a certain level to cast. Sure you may get a lot of junk if you fish in an area that's beyond your skill, but you can still fish there.
Daily fishing/cooking quests are available in the major cities (SW, Dal and IF for Allies). You only have to have one skill point to qualify, and be level 10 or higher.
Although your favorite addon for quests and gear might be useful still, the WoW interface now handles these pretty darn well.
If you're a low level Ally, DO NOT go to Hillsbrand thinking you can catch the flight point at Southshore. The place is now swarming with Horde. You WILL die. On the other hand, there's an easy road from Arathi to Aerie Peak.
The road through Duskwallow Marsh now ends in a Horde Camp. You can't get to Mudsprocket that way. Meanwhile the Allies built a bridge from Theramore to Mudsprocket. Sorta kinda, I think. But be careful, there's a big nasty Hordie at the end of the bridge. I still haven't figured out exactly how to get to Mudsprocket yet, so if anyone can tell me a safe route (for a mid 20's character) please do.
So those are my discoveries thus far. What are yours?
