They are only moving further with this direction, apparently it's their take on making the game more accessible and having more choices, despite actually shoehorning people in way lesser amount of meaningful combinations. Any possible roll back might happen if they'll see it's negative effect over time, but that might take years and probably even more years to kind of bring it back on the old rails. If it would even bother future playerbase they're trying to capture.

Running around in circles waiting for an ult dump is something that's always been in the game - its the only way to fight heavily outnumbered. It isn't a product of hybridization, it's a product of a tanky meta and sets that further encourage the playstyle.
