Flying mounts IMO are a travesty and should never have been done. They take the mystery out of the world, and make the air taxi routes less of a treat.
Flying mounts are one of the single best things ever added to the game. What's the point of having "mystery" in the world if you can't do anything to figure it out? Being able to explore anywhere and everywhere is as adventurous as you can get. Air taxi routes were never a treat.
And as I mentioned earlier, the pally shaman thing.
I also kind of liked it when Horde and Alliance each had their own unique class. I can understand the change for balance reasons, but still.
Also, taking skill points out and just giving set abilities to choose from every few levels is one of the worst changes I've ever seen.
It's not even every few levels, but every 15. However, it's not any worse than following the same build that everyone used because min maxing says to spend your talents in this manner or that manner.
And having this automatic dungeon finder is atrocious. Bring back the /LFG channel!
Yes, because hoping to find a group manually and then taking 10 minutes for everyone to actually get to the dungeon is so much better. There's nothing stopping you from joining an LFG channel and trying to make a movement on your server to get others to join. It'll probably fail because it's far inferior to the dungeon finder, but you can do it.
