The changes to city defense look very promising. People have been asking for them since before I discovered FfH, iirc. I do wonder if the building defensive modifier really needed to be reduced though, considering that culture wouldn't add any more than 25%. Of course, if you plan to add more defensive buildings to then I'm all for it.
@ Nimbus: I don't think that the packs, prides, or dens are at all related to HN, but the ability of spiders to spawn babies is. Technically they can build dens already (if on the proper terrain), but they don't seem to very often. I'm not sure why packs aren't working, and I don't know why Kael hasn't added a spawning mechanism for the Dirge yet (preferably with an option to disable it, like he just added for Orthus and Acheron)
I've been playing around with the SDK from patch H and have been able to allow HN units to capture/spawn units from combat while HN. If Kael releases the uncompiled DLL from patch n soon enough, then the next version of my modmod will let HN spiders spawn babies, werewolves create ravenous werewolves, and taskmasters capture slaves.
I'm of the opinion that the WoC and OOS errors should be handled in a separate patch. When you add this much at a time and have so many fans waiting it doesn't seem right to let minor bugs delay it, especially if there is a possibility that the bugs are from vanilla BtS (as JJR implies that they could be in the bug thread). If you release it soon then our feedback and bug reports would probably be much more helpful in fixing WoC, OOS, and any other new bugs (especially if you go ahead and release the uncompiled DLL at the same time).
