I've made the point repeatedly that India, historically, seems to have an aggressive political basis; they're like India in the Civ games where you think, hey, it's Gandhi, he must be a pacifist, then the InA starts gobbling up territory like crazy.
This entire aggressive attitude, in my view, is a problem for not only India, but its neighbors, That's why I'm in favor of the InAF / InA giving the PLA an excuse and cover to blow them up; for the Indian political structure, it's an important message for them to sit down and grow up, since India's aims of regional hegemony are not viable under the present state of Indian socioeconomic development, and even if it were, it'd be a primitive hegemony based on its military might.

The essence of your point comes out to that the InAF is poorly or ineffectively trained. The problem is, for me, training is a highly subjective factor and the counterpart training of the PLAAF is in doubt. We know that the PLAAF has made many reforms to improve the quality of its pilots, but the actual combat effectiveness of the PLAAF is difficult to have demonstrated.
The other factor I'm trying to respond to is the claims by pro-Chinese posters here of total PLAAF superiority, when what I'm trying to say is that this isn't guaranteed.

As for J-10C; it's a J-10 with some type of ECM package installed and an AESA radar with a greater aperture (i.e, more capable given the same technology level) than that on the Rafale.
The reason I don't rate the J-10C higher than the Rafale, though, is the limitations of the airframe design. Compared to the Rafale, which uses a LERX-Canard-LERX-Delta design (close-coupled, not long-coupled as on the AMK Eurofighter or J-20), the J-10C is a relatively simple mid-coupled canard delta that uses oversized canards to compensate for the canard placement issue. The aerodynamic bells and whistles the J-10C has that the Rafale and Eurofighter wouldn't, would be, first, that the J-10C has what resembles a WW2-era inverted gull wing; the inner section of the wing is anhedral, possibly contributing to better roll rates, with a flat outer wing. Second, the J-10 design uses ventral fins on the bottom for high AoA stability, like on the F-16.
The other two factors for comparison would be, first, the J-10C's higher wing loading compared to Eurofighter and Rafale; the J-10C, compared to the Eurofighter and Rafale, has about 20% higher wing loading due to a smaller main wing. Second, the Rafale is highly thrust-limited, a dispute over using inferior French Snecma engines being one reason the French left the Eurofighter project. Depending on which WS-10 derivative is used on the J-10C, the J-10C is likely to have a strong T/W at combat weights.

Regarding the J-10D, it's a rumored rehash of the J-10C that will see substantial, but as yet indeterminate, modification. Goodies on the table can easily include TVC. More aggressive modifications, in order of probability, would be CFT, AMK-like aerodynamic modifications, modifications to further increase stealth, and so on. A J-10D with at least TVC and state-of-the-art EW could easily be well on par with Rafale.
