I'll second both of those requests (Orcs and Praets).
I think part of the idea (as it evolved) was to wait until we went over to AoS completely because there are new mobs available in that package that might be used for new invasion spawns... or whatever. Personally, I think we could make that move any time. A lot of us already have AoS installed, others have offered to make CD copies and ship it if they are sent a blank CD and a SASE for it (for those with slow modem connections). Anybody who has a cable or DSL modem can download it in a couple hours or less.
I'd like to see some of those new mobs. But failing that, yes, by all means, bring those pesky Orcs back!
