Good on them for acknowledging what was a pretty terrible response to player complaints. It's one thing to be firm in your balancing decisions, but it's another thing to demean your players over it.
That said, the responses from a lot of the players were also really over-the-top to begin with. Hopefully Arrowhead is able to remedy this combativeness between the studio and the community. A live service game really only does well when the developers are on the same wavelength as their players.
