1. Complete zones, Zandalar footholds up to the point where you earn the achievement [Ready for War]. This the end of the 8.0 War Campaign
2. Next do Pride of Kul Tiras which begins with a quest [What You May Regret] from Genn Greymane
3. Complete the 8.1 War Campaign which starts with [The Calm Before] and ends with [As The Dust Settles]
4 a. Continue the 8.1.5 War Campaign which begins with [Loose Ends]
4 b. Complete the 8.1.5 N'zoth quest that begins with the Azsharan Medalion that drops from the WQ - Naga Attack!
5. Begin the Nazjatar questline which begins with [The Wolf's Offensive]
6. Work through the Nazjatar questline untii you hit the quest [A Brief Respite] which will continue the 8.2 War Campaign story
7. Finish the 8.2.5 storyline which begins with [The Eve of Battle] from Shaw on the Wind's Redemption
8. Continue the finale with the 8.3 storyline [An Unwelcome Advisor]
I skipped Mechagon but that should give your friend the blue prints to experience the Alliance story in chronological order so it makes the most sense. Hope it helps and enjoy
