I'll keep it brief.
I'm interested in:
(1) Which core would be best to begin with? I don't plan on hosting for more than myself and a few friends, nor do I plan to make a huge mall, or vast custom items, etc. I can find guides to setting up the server, so just your thoughts on which core I should use would be appreciated.
(2) The basic idea of what I want to do is rework classic instances and tune them to be the equivalent of Lv80 content. If possible, I don't want to have to recreate every mob using wow-v, rather, is there an easy way for me to simply find the, say, the "Gnomeregan" section of a database, and adjust the stats of all related mobs in there, so that they retain their spawn points/roam paths, but will in the end have the stats (and custom loot tables) equivalent to Lv80 elites?
**Edit:
The only guide to retuning instances that I have found so far instructs me to delete all the current mobs, then replace with my own. While I could do this in a delete/replace fashion (create custom, lv80 elite versions of all mobs in the instance ahead of time, and then whenever I delete a mob, immediately place a spawn for the custom80 version of it in the same place), that's just not my optimal way to do it, if I can avoid it. I also found a guide that details how to set up patrol paths for NPC's, if I have to delete/replace, so that part's covered.
Thanks in advance
