Pitches are same as they used to be. Bats have become stronger,Grounds have become smaller, Lots of T20I and IPL are the main reason batsman are becoming more aggressive and we are seeing higher totals. Its not only in India, Jo'burg saw two 400's scored on same day. Previously if any team made 300 it was gone for the chasing team, but T20 has helped remove the doubt of chasing higher totals infact it has brought innovation into game. Shots like Scoop behind Wicket-keeper, Switch hit and also the Power-play, Free hit factors count-in. So IMO theres nothing much wrong with indian pitch but with the game favoring the batsmen more.
