Im really bored of my current games though. And this game appears to have a lot of longevity, and it was only $20, so I thought, eh, why not. 21 GB download though lol gonna take me all night, and then some.
While the game no longer offers anything in terms of a challenge in PvE content and has a playerbase that has rather declined in the last two or so years (the lack of challenge has made it so people no longer think about any tactics or anything in dungeons, you just join and rush and yet still with no thought involved still come out on top) I still think it has some worth. Quite a bit of the time needed to level has been removed and I found myself at level 70 after 4 days of playing and that's while I've been attending to other things such as work, school, PnP sessions (both Basic RP and D&D) and even found time to play some Chivalry: Medieval Warfare and League of Legends.
What I'm currently playing it for is simply the scenery and the story. While no masterwork the story has some fun and cool bits and pieces to it and it's hard to argue that you could easily spend a day or two just traveling the world of Azeroth, just looking at all of the different places you can encounter.
If you're looking for something thought provoking and challenging, please steer clear of World of Warcraft. If you are just feeling bored on some fine evening and want a bit of mindless fun and some nice scenery and music then please by all means play World of Warcraft for an hour or two. I just bought MoP and a months worth of subscription but I'm not even sure if I'll play beyond that time. I'll most likely have experienced whatever content MoP has to offer me and any quests yet unfinished from Cata and that's just fine as far as I'm concerned.
However to be fair this is coming from the viewpoint of someone who didn't have to spend money on all the expansions in one go. Might be a bit expensive like that but the way I look at it if you're totally new to the game then you have also yet to do the quests of TBC, WOTLK and Cata, so it could be argued that it's worth the money you spend on it.
So not the greatest game but not quite the worst game you'll find either. Just a good amount of fun on quiet evening when you got nothing better to do. Just play it a bit and you'll be able to judge for yourself if this is something that appeals to you or not.
