I'd only see this being effective if they just pick a topic and let it be poll'd somewhere. But in the end they've done those polls on the lodestone already for interesting topics.

In the end I'd delete all posts with a similar topic(s), gather them in 1 poll, lock the thread and let the poll be up for some time. So you can clear the forums and get an idea what people think about 1 certain topic which is valued for the next update/patch.

SE is priotirizing a little weird a bit. I mean Mob sizes & Aggro signs? Noone really needed that as of now. But those adjustments are probably made on the fly and developed in less than 2 hours :P I'm really eager what they've planned in the next patch/update.
I just hope they don't set the focus to the official forums now... =X The game need to be fixed badly ;;
