I would have preferred custom variations, for sure, but this is the expected result since this is basically what they said at the premier event.
That said, I hope the variations from the beta/stress test aren't what we're getting for those characters, for the most part! Jade was one of my favorites, but I don't really want to play any of the presets she had. This could really kill some characters for me that I'd have otherwise enjoyed playing and IMO that's the real shame of this.
They say they're trying to balance the variations and that they're putting a lot of thought into their arrangements so we have to wait and see on that front. It is, if nothing else, heartening to hear that what we get at launch is not necessarily permanent, and that they're going to change/add variations as necessary.
