To be fair, "General Discussion" is just that - general discussion. It is not the go-to place for constructive feedback. There are other sections of the forums for some of these topics.
Want to talk about the lack of a healer role for 5.0?
Try the Healer Roles.
Want to talk about free companies getting the shaft for world shuffling and no compensation at all?
Try the Companies section.
Want to discuss the lack of appealing forum bans?

It'd probably help if topics were largely consolidated. I'd assume a thread with 100+ with maximum posts per page would garner a lot more attention than a couple of people spamming the same topic in new threads everyday. It'd also give a better environment for people to post feedback for both pros and cons and not have to look at multiple threads for the general feeling of a region toward the topic.
It'd also be great if people took the time to research if their questions have been asked, and answered, in the past; like that updated graphics when thread.
