Reasoning
Warcraft Tavern's Rogue guide pairs Leatherworking (Rogues wear leather, and Forever's new patterns let them scale gear faster) with Skinning, which funnels materials directly into that crafting and is separately called one of the best gold-making professions in Forever; Skinning also crafts a Lodestone camp object for bonus Attack Power. A second source agrees on this leveling/PvE pairing but flags Mining + Engineering as the alternative for players prioritizing PvP utility (bombs, gadgets) over pure gearing efficiency. Source picks: Warcraft Tavern Rogue guide: Skinning + Leatherworking; Koroboost (unverified): Skinning + Leatherworking OR Mining + Engineering for PvP utility.
