Changed to be more versatile?

Blizzard has made a few changes to the official Death Knight page in regards to the talent descriptions.

Previously, each talent tree had a specific purpose listed: Blood = Damage, Frost = Tanking, Unholy = PvP. They have now changed the descriptions to be more generic. It is assumed that this means talents are being split up between the trees to allow more versatility, however you can read it and make up your own mind here.
