1.) Is World of Warcraft good? because my friend recommended it to me but i still haven't invested into the game yet

Well I could now start a rant about how the game has lost its epicness over the years and got way too easy... but I quit right before the latest expansion was started, so I don't really know what it's like nowadays.
Yeah the game is very good, there's a reason so many people are playing it. But also very addictive. I seriously miss it even 6 months after quitting. If you are the type of person that gets caught up in fantasy worlds easily then WoW is a potent drug and you might be risking your sanity if you start playing.
And you will have to pay to buy the game + 4 expansions and also pay an monthly fee of like 15 dollars to keep your account active.

2.) How isn't your data safe?

There's a whole wikipedia page dedicated to facebook criticism:

Some of it is about data security and privacy concerns.
