Besides the original changes, shorter field and the 2 pt goal, they have since lowered the shot click to 32 secs after FO. Then since teams were adjusting to less time with long pole FO, they no longer allow the long pole on FO (though still can be used on the wings).
Personally, I would rather they not speed up the game too much. I like seeing the plays set up, and the tactics that go into the attack. Instead of FO win, sprint, shoot.
