nothing is wrong with mass gainer. It simply gives you the necessary calories to put on weight. Whey is protein without the additional calories, and it serves different purpose for different people. For me, I can never take mass gainer, because I put on weight easily. But for some, even with mass gainer, they can hardly put on couple kilos.

you don't just simply "pass the message" in a "Roundtable Discussions" topic.
