Yup, I agree w/ Spirit on this. The Quasar "powerful" doesn't really mean all that much if every team is prepared for Doublade (in which every team is). Sorry for the one-liner, but I have to go and will write more when I get back :^)
First of all, I think statistics are usually important. And these are our stats about september's RU 1760
| 1 | Doublade | 31.57351% | 31632 | 14.330% | 26568 | 14.791% |
| 2 | Meloetta | 27.00047% | 27556 | 12.483% | 21613 | 12.032% |
So it's common every team is ready to engage Doublade and Meloetta, of course. Their usage rank shows how much we evaluate their "powerful". Now, we are talking about to drop them to A+ instead of S and I think (but it's what I think about) it could be a mistake.
About Doublade I say again the same: with a great multitype like ghost/steel and despite it has only a set and it's not so speed, it's destructive and switch in when it's on field, is problematic; it's not so difficult to boost attack and its resistence does everything else. Some calcs (with other top usages):

I'll bet the same cent. If we would only a S ranking pokemon, that's good for me. Otherwise Doublade and Meloetta (here not described) drops could be not correct.
