Anet - how about ensuring more balanced matchups - both in absolute numbers and across the day before making those changes to attack/defense balance.
Being up against a server currently that paints all maps in their color at night it really takes away the last remaining motivation to try to stall their superior numbers when defending our structures. Fixing small stuff when big stuff is broken sometimes makes things worse.
Actually one of the most fun emerging gameplay situations are "heroic" defenses against superior numbers. But you wouldn't know that, would you?
