When we implemented the changes to the RNG it was actually to make the game fairer. We found that the RNG was overwhelmingly in favour of the player when on normal, and still in favour of the player in Ranked PVP and Guild Wars. Now it is still slightly in favour of the player, but not the extent that it was previously.
We are still working on tweaking our algorithm to ensure that the game is fun to play, but any changes we made were just to re-balance the game. Some players prefer more of a challenge when playing, whilst others like the game to be easier. At the end of the day not all players can be satisfied with the AI or RNG, but we are trying our best to make as many happy as possible.
EDIT: To clarify, it is PC that is has had the combo breaker changed to be fairer. This combo breaker will be implemented on console with the next update, which should see console cascades be less streaky.
