Thanks for all your thoughts. Having read all the responses and FAQ, I have to say I don't like the FAQ ruling. Mostly because I don't see why they did it.
1) I don't think it is *that* hard to look for a weapon keyword to tell whether get the bonus or not. Gee - some powers say Implement, some say weapon, maybe sometime there will be those that have both.
I read that FAQ ruling and I get the sense CS was trying too hard to say "Yes!".
2) From what I can see the RAI, because of the existence of the elemental feats, you were not suppose to use weapon focus with implements. The FAQ ruling obsoletes the elemental feats for 1/3rd of the wizard build and anyone else with a implement which can be used as a weapon. I also suspect that implement choice was not suppose to be affected by can I use weapon focus. As a house rule I will probably ignore the FAQ, and further clarify Weapon Focus by saying it only works with powers with a Weapon keyword. I'm aware there are problems with the elemental feats, but "fixing" them via weapon focus seems a sub-optimal fix.
