You gave no reasons for the choices you made on the set, as well as no ev's. How do we know that its a defensive rotom?
Also, those are terrible reasons. Those are given, and are very well known.(BTW, the first three are almost the exact same)
There is already a defensive rotom set on smogon too. This would be like adding to the move options. But from what i see, it looks more like the annoyer set.
