Just finished the 7.2 PTR Warrior Campaign, and I have a slew of screenshots to share.
First off, it's pretty short. I missed the early screenshots but you get the introductory quest to report to Odyn upon zoning into the Skyhold, after which he directs you to Aerylia (the Skyway teleport master) to send you to Helheim to recover Helya's Horn and liberate the Kvladir. Upon arriving she gives three simple quests:
The third of which takes forever (probably due to bugs, which have been reported). Took me about 25m, but assuming the issues are fixed, it shouldn't take any longer than five. Afterwhich she thanks you, and returns you to the Skyhold to report to Odyn again.
Again, I missed the picture, but the group in front of him were Vrykul, who he turns into Stormforged with a burst of light magic. Next, you're sent to the Broken Shore to report to Danica. Oh, and apparently you're in charge of the Kvaldir now.
The quest to get Crowley/Eitrigg (Horde variant is exactly the same) is offered by Danica, and no explanation is given as to why Crowley/Eitrigg is "leading their forces" or why the Valarjar have even ever heard of him. In my opinion this is supremely bad storytelling and unfortunately doesn't get any better.
His quests are pretty simple, just go kill a couple things while he tags along. Most interesting though is that he still provides the "Rebel Valor" buff from way back in the beginning of the Gilnean starter zone, which increases haste by 100%. It's almost definitely a bug, but it's pretty awesome if you happen to have the movement speed Legendary boots. After completing his quests he leaves for the Skyhold.
...with absolutely no explanation as to why he's even aware of the places existence, much less allowed in. Again, this is supremely bad storytelling, and also exactly what I suspected, which is why I argued against his choice as our newest follower to begin with (see the relevant thread in this forum).
To finish up in the Broken Shore, the Kvaldir quest is very simple: Blow horn, summon Kvaldir allies, find portals, blow horn to destroy them, report back to Danica for a prize.
The toy is basically power-posing; I recommend using it before attempting raid bosses or public speaking.
You also recruit Crowley/Eitrigg (and the active follower count is increased by 1 to allow him to be used without deactivating any other Champion).
Note that all Champions gain a 3rd equipment slot available at "Titled" quality which requires 200k experience after Epic. Crowley/Eitrigg's abilities haven't changed since my initial report last week, and are still unimpressive with the uncommon bonus being a duplicate of Svergan Stormcloak's bonus. You also unlock Tiers VII and VIII of Order Hall Advancement. The initial research for T7 takes 1hr, retraining it takes 3 days, and Tier VIII takes 14 days.
*Roster of Champions allows a total of 7 active Champions since completing the campaign also increases active count by one.
*Don't bother asking about Relic Empowerment, nobody knows yet.
Finally, the Class Hall mounts were not unlocked upon completion, although they may simply not be implemented yet, or require some follow-on chain. However, you can see them in the Mount Collection tab, and their color variations change with specs. Keep in mind that this is not necessarily final, and it's completely possible that every spec could end up with every color variation anyway, and please no complaining that your favorite spec isn't also your favorite color, I quite simply don't care:
Arms - Red
Fury - Black
Protection - Purple
Whole thing took me about an hour, so it's pretty short, and in all I'd say it's pretty good, except for the lack of explanation given for Crowley/Eitrigg's involvement with the Valarjar. Fun as it may be to tie in some faction-heroes (and I've argued before that they should have been included from the start), it simply isn't explained, and that leaves some pretty huge plot holes. I'm also very disappointed that Trollbane/Saurfang don't appear to be involved in 7.2 at all, despite being the players initial introduction to the Warrior Campaign - they may be "too big" of heroes to be placed under our command, but it'd be nice to at least see them around Deliverance Point, providing Command and Control as befitting their status as legendary Alliance/Horde wartime commanders.
As a final bonus, Aerylia's option to teleport to the Broken Shore remains, although it currently takes you right back to the quest location in the middle of nowhere. Hopefully, this will redirect to Deliverance Point on live.
