This patch is comprised of adjustments that will help tune the live game, potentially shift the meta there, and also line up with the eventual transition to OW2.
Some lean more to the experimental side, such as with Orisa and Sombra, but we're interested to see how such changes impact their playstyle and strategies such as double barrier.
Many of the other changes are relatively small but are aimed at improving the gameplay feel of heroes and their abilities rather than adjusting much power.
The Experimental Mode allows players to try out potential new balance updates, game modes, and rule changes. The content within this mode is not guaranteed to be released and the mode may not always be available.
