Well, I think the 152 is better than all the other 190s. Not by much, and in some aspects it's a lot worse, but all things considered it's more of a killer than them. Any more than the D9's ENY would be too high, imo.
The 47N - It's a hot rod, not just A2A but A2G.. I think the ENY is really close to what it should be. It's not hard to argue that it's better than the 51D (on an ENY scale).. So what's left? 6 or 7, or 5 as it is. No big deal in this case..
