Yep, they should bring it back.....maybe even reduce icon ranges to 3.0 during the night hours.

Also, they should set it up so it isn't night in all arenas at the same time. Maybe one on central time, one on GMT, etc. That way those who prefer daylight can go to another arena, whilst the night fighters can continue their play in the arena where its night. Might just help populate all arenas a little better.

[EDIT]
If nowhere else the AvA might just be given night time. Might even tempt a few to join it just for night fighting.
