It was better than GOATS by far, and it required far more skill to pull off.
But ya, it got boring over time.
IMO the devs should have looked at the synergy of DVA and Winston. The key here is that they can both jump the same distance, making them good dive partners. One solution could have been to give DVA the same amount of jumping power (overall duration), but make sure that she could not make the full Winston jump in one go, but instead would have to land and recharge a bit between. Just a few seconds of mismatch would have made dive significantly harder.
I don’t know, of course that would have to be tested, and Im not sure how unpleasant DVA would have felt, which is also important. Testing, testing, testing. I am convinced a game balance solution could have been found.
