It's close, yeah, but you understand my thinking. Implement users are still kind of hosed compared to weapon users, and I mind less.I'd say Staff of Ruin falls at least very close to being in the same category. The case with implements is a bit more complex since most casters will want to have other ones at least for specific purposes and using an SoR effectively may well require several feats, so it isn't quite so clear-cut. On top of that at least some casters seem to need a decent way to stack on a bit of extra static damage. I'm not sure though that would be true if the other 4 items were out.
