I suppose it depends on why the skill was "fun" for you. Was it because it laid waste to everything before you, or allowed some sort of exploitive behavior? Yeah, that might get nerfed.
But one should probably expect that (since it performs above & beyond), and rather than being surprised at the nerf, be surprised that it took this long to get nerfed.
If you're talking about the sustain changes, this is what I realized: The game is more fun when using some heavy attacks .
Aside from heavy attacking yourself, others using heavy attacks give you the chance to use game mechanics like dodge roll and bash attack in a meaningful way.
