Yep I'm with @Iara on this one, although we use him in different ways. I hated rav for a long time too xD but he became my pvp boss card.
The stat change is fine, and a buff if you will. I agree the atk is better than the support (if not simply because as I said, for his skills atk does a similar job as rec but is also useful in other ways (such as Iara's usage)) but that's not the issue.
The skill swap is what nerfs him for me, and even looking outside myself and my own usage - all it does is put him in the same toy box as mons like shout and lady dev, with rav being arguably worse than either. Swapping the skills takes away the individuality of rav - even if it makes him viable on a 'my first sp+ everyman team'.
