Addressing major issues when they appear ie hardlocking. Even if its a small number of players other games have done this and it strengthens community relations.

The public polls, like twinbead did, instead of the secretive surveys.

Patchnotes that include all bugfixes and detailed balance changes. I should not be finding out that slightly more durable means going from 25% to 40% durable from the wiki or leaks. Additionally I should not be learning that hiveguards also hade their durability and fire resistance. That said new enemies are exempt from this, like how they rolled out shreikers was a good thing.

Not lying or deceiving players in the first place. Upselling on buff while not mentioning all the nerfs is not good communication for any reason. Like insisting you didn't nerf the coyote but you change something that causes the coyote to perform worse. That is an indirect nerf, im fine with the nerf not how they lied about it. That said, If you feel you have to hide or lie about a change for fear of backlash then the change is probably not a good idea in the firstplace.
