....Blizzard alone is notorious for balancing their MMO and online games towards PvP play.

"Notorious" according to who exactely? Are you trying to express and share your own opinion? That's fine, I disagree but respect your opinion.
Or are you trying to say that's a commonly shared opinion everywhere and that everybody would say the same? Because in that case I would have to disagree again.

Btw, if it helps you in any way, I've been playing (and still play) WoW 'till patch 1.6 (altough I played a bit of beta too).

"Notorious" according to who exactely?

Anyone who plays the game and have played it all through 2004, even though in Cata they're not as bad about it, but it's not exactly unknown to gamers Blizzard isn't good at balancing PvE and PvP.
