I think it absolutely can. I actually use Counterspell now as a wizard PC and as a DM. I would never use it before because it required this silly guessing game about the level of the spell. Now it’s usable.
I think I would agree with
@Gladius Legis , every change is an improvement.
Don’t get me wrong I too would have liked a few more changes. I would have liked to see them keep the save against grapple at the end of each round for instance. But I don’t have a problem with iterative change over a slower period. Evolution of 5e not revolution.
I totally accept the comments about power creep but I think that as a whole the game is more fun because of the changes and difficulty is a dial that you get to turn relatively easily either way and is wholly within the control of the DM.
