So I've been leveling up my Sorcerer in preparation for PvP, and I've noticed a few tactics that I haven't seen beta tester footages taking advantage of. For instance, you could spec in the Storm Calling tree and get a knock back effect that essentially knocks your enemy back on his ass and like 15 feet away. I was actually able to "morph" it so that it has an additional stun capability. This is a great utility type spell to knock away melee types so that you can blast them a few times from afar before they close the distance. Also, I've noticed that you can block melee attacks with your staff. I blocked sword attacks against me a few times and it even stuns the melee if he tries to take a major swing and is then blocked. I'm sure people will discover a lot more elaborate tactics when the game is released.
