The mage guide is absolutely not updated for P4, a lot of good items from ZG are still not in there: Larme de Chaos, Bague de servitude, Charme de héros zandalarien, Volonté d'Arlokk (for evocation)... Pretty simple: use your brain, don't just follow the guide blindly.
The priest list is an absolute joke, so many items you shouldn't ever take over any caster. Please remove this list and put something at least somewhat accurate, this is completely misleading !
The warrior BiS guide also has some problems and lacking good items:1.) Head: Couronne de destruction and Couvre-oeil de Dagharn is not listed at all, while it's good (optional) for those who have enough hit, or don't have the time / money to get Heaume Coeur-de-lion or do PVP.2.) Shoulders: Espauliers griffe-de-drake is put as just "Optional" while it's clearly better than Epaulières de champion en plaques (+3 strength; 20 agility = 1% crit, not counting Esprit des Zandalar)3.) Back: Cape surpuissante is obviously the best, but (not listed) Cape de puissance draconique is a close second (becomes best when the warrior has enough hit). Cape gueule-de-feu should be listed as optional (with the caveat: rogue prio). (Not listed) Cape zulienne en peau de tigre is also optional when the warrior needs hit.4.) Chest: (not listed) Haubert runique taché de sang is on par with Armure de légionnaire en plaques (optional).5.) Wrist: Garde-bras de redresseur de torts zandalar should be listed as optional.6.) Hands: (not listed) Gantelets sacrificiels is BiS for those in need of hit / not horde / don't have the time or money to do PVP. (Not listed) Garde-mains du maître des tranchants should be optional for those not orc/human.7.) Waist: if Ceinturon d'assaut won't drop and the warrior doesn't need hit, (not listed) Ceinture de redresseur de torts zandalar or Chaîne de Therazane becomes a good choice (optional). (Not listed) Ceinture de têtes préservées is also better than Ceinturon de Brigam (optional).8.) Legs: Jambières de voltigeur en plaques is added in content phase 6, so shouldn't be listed. Pantalon du coeur noir (BiS) is not listed, while clearly better than Jambières de légionnaire en plaques (1 strength = 2 attack power). Cuissards du croisé déchu should be listed as optional for those who don't have the time / money to do PVP / fight for world bosses (or not using the Devilsaur set).9.) Feet: alternative BiS Bottes de la Flamme d'ombre should be listed (caveat: rogue prio) - because Bottes chromatiques should be first given to (fury-)protection warriors. Bottes en mailles sanglantes is listed as optional, so (not listed) Bottes du Déchirevent should be there too.10.) Ring: (not listed) Anneau de Précisia should be optional (caveat: protection warrior and rogue prio), while it doesn't have str/AP and only 0,8% crit, the 2% hit is huge.If the guide's original author doesn't have time or the enthusiasm to update the warrior BiS list, I would be happy to do it and help the community.
