I don't get why everyone wants to change the 3 point line. There's only a few players like Curry, Klay, and Korver. Changing the rule for the outliers is never a good idea. The league as a whole is actually shooting worse from the 3 point line (obviously because teams are emphasizing 3s over long 2s). So the "it's easier narrative" doesn't hold for me.
If you're talking about offensive sets and aesthetics. I'll strongly disagree. In order to get those 3 point shots it requires lots of teamwork. The most aesthetically pleasing offenses (Spurs, Warriors, Hawks, Mavericks) are those that value the 3 and move the ball well.
Keep the game as is.
I think any suggestion of moving the line back would be based on the assumption that the trend towards three point shooting will continue until it verges on the absurd (I'd describe > 50% of attempts from beyond the arc as absurd), not on the game in its current state. I notice for example that you didn't list the team that takes the most 3s in the league on your list of aesthetically pleasing offenses. People don't generally seem to like watching the Rockets in my experience- part of it is probably the flopping, but part of it is also the fact that every possession either ends up with a 3
(which they don't shoot all that well, they just understand math enough to know it's still a good shot at 34%) or at the foul line. Gets kind of boring.
That said, I'd rather they give defenses a chance to adjust and improve their ability/prioritize guarding the arc before doing something extreme like changing the rules. Especially since a rules change would probably mean widening the court or taking away corner 3s entirely, which would kill spacing.
