I could just download it free off a certain website.

However I will not be able to play the Online mode.

I only spend money on games where online is the most important part. I could even borrow a friend battlenet account and just play out the single player.

The online on the other hand has me interested.

What about the PVP mode is that something like HON? What features does online have thats worth getting it for?

If I could play this for like 4 years simply because of the online I would buy it.
