There was some nice analysis on 538 showing that this is going to matter even less than people think it will (which isn't much to begin with):

That said, I kinda hate this, and probably a little irrationally given how little it will really matter. Still though, I hate it.
My issue is that I think ANYTHING that ultimately decreases the importance of touchdowns (and everyone but the kicker) and increases the importance of extra points* is ultimately really stupid. Driving down the field and scoring a touchdown is really hard, whereas kicking a 34 yard field goal is statistically really easy and ultimately just comes down to chance. In my opinion by moving the extra point back the NFL has ultimately ever so slightly decreased the relationship between skill/performance and victory while increasing the relationship between chance and victory. I think that's dumb.
I also think this rule change over-corrects for what the ACTUAL problem was, and in an inferior way to a MUCH simpler solution to that problem.
The problem was that extra points are a waste of a play. The solution is simple: a touchdown is worth six points, and you can either go for two to get eight points or simply defer the option to go for two for one point. That's it.
Instead of that we get 1) 94-97% of extra points STILL being stupid and wasted plays rather than 99% of them, and the other 3-5% potentially affecting the ultimate outcomes of games in deference to luck over skill. Ughhh. rather than fully fixing the problem in a wildly easy way it just fixes the problem 3-5% of the time and introduces a new problem in the process.
*You cannot increase the importance of extra points without decreasing the importance of touchdowns and field goals, and by introducing a higher failure rate into extra points you are by definition increasing their importance,
