The wiki pet guide
http://wiki.project1999.org/index.php/Pet_Guide includes the DW change.
If mage focus pet info is incorrect (I don't play a mage) then perhaps someone should provide the correct info?
What is the point of saying "that info is not correct" and not providing any help?
The wiki is and will always be, by its nature, a "90% correct/complete" resource. Well that's better than 0% yes? And certainly better than any other classic resource. If people want to help they can push it towards a 95% correct/complete resource.
The boil blood line resist checks are "correct" as far as they can possibly be from parsing spell data. Details of server side resist system changes were not released with Uthgaard's massive spell update at Kunark launch.
