I have long been wondering why some abilities with a cast time seem to take much longer than others, so I did some testing.
Edit: I did some retesting and found that the results below are not correct.
You can cast Crystal Fragments and Dark Flare much quicker, same as Wrecking Blow or Snipe.
There is however still a difference between those skills:
Dark flare and Crystal Fragments have animations that are up to twice as long as their cast time. The animation time was so long, that I did not hit the ability key fast enough during my initial testing - that is why my results are wrong.
While restesting I essentially kept mashing my ability key over and over and found that by getting the right time for initiating the follow up cast you can have the projectiles hit at almost the same rate as the tooltip cast time.
However, the long cast time remains an issue with sorcerer pets as you dont spam them so often.
I still think updating the animations for the skills concerned would make their use feel much better.
Here's what I found:

As you can see, you can land two uppercuts or snipes with only 1.2 seconds in between them, so the deviation from the tooltip is only 0.2 seconds, which could be influenced by lag/measuring inaccuracies.
However, if you cast two Crystal Shards or Dark Flares right after each other, you will notice that you spend up to 0.8 seconds longer casting than is stated in the tooltip.
Cast times for summoning Sorcerer pets are also by far longer - about
0.7 seconds longer than stated in the tooltip until the familiar icon appears (takes at least a second longer till the familiar is actually visible and starts considering if it might join the fight).
