Hi, our guild recently started clearing Ulduar and Naxxramas for fun and I see that Ulduar kills are counted to the PvE Ladder but Naxx's aren't. My suggestion is (if possible) to include the oldest-tier raids in the functionality too. I think it may be some additional boost to the interest in them. Atleast it would be a motivation to us and I think we won't be the only ones.
