They have some volunteer from the fanbase to read them. They have a specific rule they must follow.
Before a single piece of feedback that is negative or to do with balance, requests, etc, they must provide at least 10 pieces of praise and blind acceptance feedback.
The feedback is also sent right to a spam folder, and is always sent a month or two late. So when it gets to them, they have usually made an already bad balance idea, or they miss it due to it being in a spam folder; or they do it on purpose and by the time they consider taking feedback and doing something based on it they’ve already got multiple other things being presented on the forums in need of change.
