So.. be on hold for 45 minutes to talk to someone that may or may not speak English, won't address any of your concerns that aren't in their scripted responses, and won't forward your feedback to anyone because they're an underpaid phone jockey?
No, this is a much better place to voice concerns because everyone has an opportunity to see and respond to the topic. If the devs are doing their jobs, they'll be passing these concerns to their higher ups. If the higher ups are doing their jobs, they'll be working on a way to regain player trust, which was supposedly their goal when they changed up the dev roster.
