We think the community/social side of things is hugely important Raiman
We've a host of long term and short term ideas for game content. Ideas that we're not yet happy enough with to share - We want to polish these up. Ideas that may never come to pass - We don't want to get folks excited about a change only to never bring it into the light of day.
A graphical overhaul would be very delicate. I wouldn't be wrong in saying it could go very badly. Some love the game as it is. No flashy colours, no comical knights or puffing mages. Having said that some (dare I say 'tasteful'?) changes are, I think necessary.
As you say, resources for these changes are not flowing readily. We do hope to correct this though and this is another trail that our 'ideas wagon' must follow: the means to correct the current lack of resources available.
