This game really isn't an example of 4th edition. Yes there are skill checks in 4th edition and the classes have the same or similar names to third and second edition. 4th edition is over anyhow nobody likes it In my opinion Third edition is terrible. It revolves around splashing in various classes and creating hodge podge…
Its hard to say I am not going to play the guardian until its fixed. At level 2 I wasnt getting knocked. But I can tell you it does not block melee or missile damage
