Also get the Heirloom Mount. Being able to have basic riding speed from the beginning will save you a lot of time if you're starting from level 1. Allied races start at 20, so this is a non-issue for them. It's important to note that Pandaren can not use this mount until they finish their starting zone and pick a faction. Being Horde or Alliance is a requirement of the mount.
Battle Standard of Coordination: This item gives you 15% bonus XP if you stay within 100 yards, with a 10-minute cooldown. Can be useful if you are grinding in an area or when completing a dungeon. If you plant the banner at the last boss of a random dungeon you will get 15% extra from the bonus XP as well as that XP is awarded when killing the last boss. You need to be friendly with your guild to get this. The easiest way to get it on a new alt, is to buy a Renowned Guild Tabard with you main and send it to your new alt. Now you need to join a guild with the “A Daily Routine” achievement completed. So open the guild finder, if you’re not already part of a guild, and look for a guild with a lot of members since they are more likely to have the achievement, and ask to join. Then buy the Battle Standard of Coordination.
On January 30, 2018 Battle for Azeroth was made available for preorder, coming with the unlocking of the four first allied races. With the announcement of the Collector's Edition and release date for Battle for Azeroth on April 5, 2018, Legion was the first expansion to be offered for free with a preorder. Battle for Azeroth is the first expansion to launch in the Americas, Europe, Taiwan, Korea, and Australia/New Zealand at the same time. Battle for Azeroth became the fastest-selling World of Warcraft expansion ever.
I made some route changes to the Horde levels 43-44 sections. I have swapped 44 Dustwallow Marsh with 44 Desolace (the entire sections). This allowed me to do Deadmire (at lvl 43 instead of 38) and then go stop at TB to turn in Deadmire + The Black Shield at the same time, then fly quickly to do the Desolace stuff. Doing 44 Desolace is now mandatory because I think its faster with the new routes. This will also make the level 53 grind much shorter. I think these were great changes.
TL;DR: Champion equipment is an investment for long term profit. Two different type of equipment, one raises % of success, other gives back materials on mission completed. Best item is 10% per troop, but you need 1 Ofuscation Vial. Magnetic Mining Pick and Disenchanting Rod are the best ones in material returns. You can break even with investment sooner than you think.
