Before you try to convince me it's really ugly, under certain speeds it plays a lot better than a perfectly curved slider. This would now take at least 5 points to make, not to mention the time required to actually move those 5 points to appropriate spots.
As I said before, it's still possible using the red dot at the end, but then you have to find a new spot for the middle point, which is somewhere closer to the endpoint to prevent the slider having imbalance.
Consider even more extreme variants of this as well.
I am not against the new feature at all, I just don't like it being forced because there was absolutely nothing wrong with the old way of doing things. Time invested for something I liked to do before has just been doubled and I don't really see it as an improvement.
By the way the new system rocks when creating symmetrical patterns, and I really love it, however sometimes it's just not "the thing" I want.
