How are the overall sales looking for the PC version? Not as in numbers, but compared to expectations?
Are you getting sales spikes in India each time they get a "surprise"?

Not really, the issue becomes one about how many of the pirates would have every bought the game in the first place. Particularly in developing markets the research has demonstrated the potential for piracy to have a positive effect on sales, with the piracy basically acting as a demonstration of the wares, and pressures from issues with the piracy leading to increased sales. That is, many people who never would have otherwise bought it, having gotten a feel for it, at such a time that piracy is not as much of an option (i.e. a business that is "going legit", the software no longer can perform as pirated, etc.) many will actually buy the product legally. This is essentially an effect of the set of people who would buy the game and the set of people who pirated it being nearly separate.
To be completely honest I have a suspicion that sales figures in India will actually end up being fairly positive a version or two from now should you find an effective way to prevent pirates access to the academy and mods (and do other things) be found.
Another thing that could be beneficial is that if there are that many people who are willing to play a buggy, twitchy, pirated shadow of a version, you could look into the viability of making a DBC 14 "Lite", which has no access to the academy, mods, and has locked very basic team and match type (and conditions) settings, then see if any advertisers would pay to have their adds put into the game (basically the same way people make money off free mobile phone games). If there's such a number of the pirates, you could kill two birds with one stone by giving them basically what they have no, but without the bugs, actual support from the company, a chance to make a bit of money off them and of course the drive (more features and such) to buy the proper game. It would also be a tutorial on how to use steam (if you could get such a "Lite" version on steam) on how to buy the game properly.
