Possibly a Idiot.
I disagree. The avenger motivates enemies to stick together closely, yes. But that allows your party to capitalize on blast and bursts, which most classes have at least a few of at encounter level.
I do not see how this disagrees with my point of view.
This means any reasonable enemy will be forced to attack the Defender, and that permits the Defender to fulfill his designated role in the adventuring party instead of standing around feeling like a defective Striker.
Moreover, it is going to force the enemies to either hold a front-line formation around the two of you, or split up and let you use your Oath of Enmity double-roll to decimate them one at a time.
This does not work as well as it sounds. It causes the defender to use up an excessively dangerous amount of healing surges, and the powers that defenders get to protect end up being dead weight. Additionally, it isn't hard to hold a formation in a slightly cramped environment, such as a dungeon.
Now the point about a defective striker made me chuckle, because to me the avenger feels like a defective defender, who wants to be a controller, but doesn't realise he is supposed to be a striker.
