Currently this is a vague discussion question that seems to want to compare Titanfall 2 and "classic" CoD ("classic" is in quotes because I am not sure what you mean by that as CoD was around a long time before it got popular or the Titanfall 2 developers had anything to do with it).

Here are some suggestions:

1. Pick one topic and take a position.
2. Support your position with descriptive facts and arguments.
3. Opinions are fine, but they are only interesting if they are informed, detailed, and from a point-of-view. So, someone saying that they "like supporting games that stay true to old school roots" is really boring because: 1) we have no idea what you mean by "old school roots" - what exactly in a shooter makes you like it (not when it came out, but the game mechanics you like or dislike), 2) you've stated you have not played Titanfall 2 and thus are less informed about the subject that most gamers, and 3) while you do establish that this is your opinion, you don't tell us anything about why you feel this way. . . what is it about the game mechanics you enjoyed in whatever it is you mean by "old school roots" that makes them appealing to you as a person. . . do you have fond memories of playing them as a kid with a loved one? Were these the first games you became skilled at playing? etc.
