It would be very interesting if DDO devs made some system (it's relatively simple to make) which allows us to submit ideas and other people to "sign" (vote).
This is an example of what I'm talking about:

In this specific case each account has 10 vote points. You can give up to 3 votes per topic/idea. I don't know how long it takes to give your vote points back though...
They could make it accessible only to VIP/Premium accounts to avoid spamming (creating multiple accounts to vote for something) (sorry f2p-ers).
That way they could get efficient and realistic feedback from the community as to what we want. And it doesn't mean they HAVE to do what's on top of the list, it just helps get better input from those of us who are every day dealing with stuff in game
