Should I get MoP?
 

I used to play WoW vanilla and then Outlands, but I heard the game has changed a lot recently.

My question is...

If I get MoP, do I also get all of the previous expansions?

Re: Should I get MoP?
 

All expansions are separate. In order to play MoP you have to get them all.
The Burning Crusade
Wrath of the Lich King
Cataclysm

Some people like MoP, some don't. I personally like it. A lot to the game has changed and I think for the better.

But for me since I reached maxed lvl all I feel like I am doing is dailies. Gets boring. So I am taking a short break.

There's a free 10-day promotion going on for MoP. If still interested, you'll probably want to check it out.
I've done the same and started the 10 days on my main character to see what it's like. Not sure whether I'm going through with it though, since I quit in December 2011 and missed out on a lot. You know, achievements and the likes.

The expansion itself is pretty good though, IMO. Blizzard's done a nice job at the Pandaren areas and race, as well as changing the way the totems of Shamans work. Same goes for the glyph, talent, pet & mount system.
