This is for PvE and PvP.
Open a discord thread for suggestions. You can make one for them (probably ran by a bot, so a person has to type !suggest blblabla in bot chat, then it goes to the channel and pepole can vote with emojis) and one for discussion. Like most servers do. Many people can't be bothered to go to forum to submit their thoughts, it's way easier to use discord, and this form of communication is preferred espacially by our beloved PvP community.
