I'd say you're right.
However, I will slightly disagree with you about the talent trees.
Many WoW purists praise the old talent trees. I for one, feel as though they are archaic. The new trees introduced in MoP have been a welcome change. Of course there's the cookie cutter specs, but let's be real here, there wasn't much tweaking going on with this old talent trees because nothing was ever really balanced around them.
Even through Wrath, there was very little deviance from the established "best" talent picks.
While currently there are some clear winners, I really enjoy having to change a talent to accommodate a playstyle and/or boss fight. While the old talent trees have very little deviation.

I by no means will play Classic.
I'll admit it, I am a Wrath baby. However, leveling through the 1-60 zones was painful. The old dungeons were horrendous. I hated having to travel all the way to a dungeon just to get in. I hated running out of quests and mobs to in a zone without hitting the appropriate level to move on.
I would definitely say I was a hater. But now I am a well-wisher. I want it to do well. Because that helps the game overall (my speculation/hope).
I just hope that the people who really wanted legacy servers show up and live up to their word. Because if they somehow falter, that won't bode well for legacy BC or Wrath servers.
