Intamin simply just made an oops moment on Maverick. It was a design flaw that somehow got overlooked through design, fabrication and assembly. Not sure how it made it as far as it did, but who knows.
I recall when Maverick's heartline roll was installed just how off it looked, especially from the bridge that allowed you a clear view right down the center of the element. Heartline was practically non-existent (appears to rotate around the centerline of the train chassis) and the rate of rotation appeared to be really high for the distance traveled and the expected speed. It always just looked wrong.
Velocicoaster has greatly different (better) shaping, it's clear to see in photos and in person. It's a far larger element with a much more gradual rotation around the centerline. It just looks correctly designed, which obviously it is, which wasn't the case on Maverick.
Looking at videos of both for my own curiosity and breaking it down into some big assumptions, Maverick appears to complete the entire roll in about 1.2 seconds from entry to exit. Velocioaster is about 2 seconds. If both moving at say, 55mph (both are quick at that portion), we are looking at ~96ft of track traveled on Maverick compared to ~161ft of track on VC for each element. Maverick enters and exits at higher bank angles, so assuming it rotates only 270-degree total, it's rate of rotation is approx. 225 degree per second. VC enters with almost no bank (exits with some), so assuming something like 325-degree total, it has quite a bit lower rate of 162.5 degree per second of rotation.
I'd guess that an extra ~60 degree of rotation per second is quite significant, when already at a high rate. No question this would bump up the stress on the train and reduce rider comfort, especially when that heartline was practically non-existent. Would be interesting to hear from more people who have experienced it before it's removal, just to hear how it actually felt/rode.
If I'm not mistaken, the number of people who experienced it before removal can be counted on one hand.

I know that list includes Sandor, my best buddy. I watched it cycle with the roll, and it didn't seem that big of a deal from a rider perspective. The direction changes are already pretty crazy. But I'm just eyeballing, I didn't do the math.
