The some of the walls look textured in a way that might be making the shadow
edges more pronounced, but I think Josh is probably right about it just
needing more points to each area light. I don't know what Moray's setting
for that is like, maybe it shows you a 3 x 3 grid by default though. Often
it'll take double that for real good edges.
Hope you give radiosity a try too.
