Some huge (and tiny) news coming out of the PTR today, as we're finally getting some mount size adjustments for Gnomes and Tauren! This has been a long-standing issue since...well since Vanilla really, with Tauren getting stuck on doorways and a lot of the mounts for both races never looking quite right. Well, today Gnomes can catch their mount's reins for the first time and Tauren... well they might fit through some doorways. The change only applies to "normal" size mounts for Tauren, as smaller ones (like hyenas) remain unchanged. Blizzard can now also fix issues where some mounts appear too small for certain races and they're looking into it.
Some quests in my guide are marked as "SKIP" and colored in red. These quests are simply either too hard to solo or not worth the XP/time and are skipped. My guide will only list SKIPPED quests if the quest is a direct follow up after completing a quest, not one that you have to click the NPC again to get it. If you hover over the skipped quests, it will give info on why it is skipped in the guide (unless that info is already listed directly in the guide text).
2. Achieving. There are many pet battling achievements in game, and following the natural trail through the Taming [Continent] achievements up to Pandaria, and then on to the Spirit Tamers, Beasts of Fable and the Celestial Tournament was an epic journey for me and for many others. It's well worth doing. The Celestial Tournament is still, IMO, the pinnacle of PvE pet battling. However, WoD and Legion and BfA have added more battling achievements.
