Well, I'll give a few more suggestions:
1) Based on the comments that 'Jeff' made, he was probably an inexperienced player who played quite a long time ago, before many of the modern changes, most of which have been for the better. I would recommend asking a veteran player who has experience in many card games and understands the math and concepts behind them, rather than what appears to be a casual player who did not participate in the community much, if at all. Getting multiple points of view is also a good thing.
2) Any criticism that you receive on that article has no bearing on your own CCG's quality. Your game might be good, maybe better than Elements; I have no idea, as I've never heard of it before now.
3) Remember that because, by definition, everyone who is on the forum obviously likes Elements and stays, that they are more likely to deliver criticism towards a negative article, and that this should be expected. It should not be taken as a personal attack, if it was taken that way by you.
4) Elements certainly has its negative points but the interview focused either on nonexistent/misrepresented issues or on Jeff's opinions, rather than the actual flaws of Elements. For instance, Jeff claimed duos are not viable and that weapons are overpowered, but did not mention any of the most powerful broken cards like nova, which was in the very first version of elements.
