I think it is worth bringing attention to this here in case you missed it in ESO Live last Friday. System designer Cullen Lee was giving a house tour of the new Elinhir Arena on the PTS. During the tour he mentioned that one of the influences behind this houses creation was from the feedback that players in the community gave around wanting to have an arena. He also noted that practically every suggestion is read by the team responsible for housing. He admitted they don't comment on the threads but rather "lurk".
I think this is good to hear. Sometimes it can be frustrating for those of us who love housing in this game to feel sometimes like our suggestions are not being listened to but it was promising to hear from a dev that they read so much of our feedback.
Perhaps it would help to see some comments from you guys on the housing forum every once in a while to remind us all that this feedback is being heard.
