Yes. I still believe that if you can't win your conference, you shouldn't be called "national champion". I say this as a Buckeye fan, who is happy to see his team moving through the playoffs, under the current structure, but doesn't like what the structure has become.
Also, I believe that conferences should be balanced so that the champion of it is obvious, which means going back to divisions or smaller conferences, and playing even schedules within that structure.
There's what 130 or so teams in CFB? Ok, 13 10-team conferences, playing 9 games in conference and some at large games, no conference championship game needed. 13 teams get auto-bids +3 at large. Conversely: 6 conferences of 20 teams, broken into 10 team divisions. 9 division games, 3 other games, conference championship between division winners, as a defacto play in game. 8 team playoff with 6 auto-bids and the 2 best runners up.
Either way, I'd rather see the conference championships matter more, bowl games matter more, or at least have more good matchups, due to the diluted playoff.
The more we expand the playoffs, the more the regular season doesn't matter, and I hate that for college football.
