Hey guys, so I wanted to add onto this since I've had the opportunity to test it on two more characters alliance side and really focus in on when it changes over to 295.
So I did drustvar fully, accepting both 295 pieces, and the first azerite quest in tiragarde sound. I had previously thought the dungeon quests played a role in this but, I don't think that's the case. It's story completion (or well getting 4 azerite pieces from quests ((not scrolls quest.))) So I tested this and rushed half of tiragarde and got the dungeon quest done there, as well as drustvar, expecting my rewards to change to 295 being offered after abandoning quest and logging out/back in. This didn't work at all. I *HAD* to finish a 4th storyline and receive another 280 piece before I had the remaining pieces swap to 295. So I completed the pvp campaign, which i usually save to be a 295, but since i'm faction changing, i'll have another opportunity at one anyways.
Once the 4th quest was completed that rewarded a 280, excluding scrolls quest, so in this case, 2x drustvar, 1x tiragarde, and 1x war campaign. I was able to abandon the 2nd tiragarde quest, relog, and then the rewards showed as 295 instead (note: just abandoning *DID NOT* work. I HAD to relog. I was getting pretty worried I had wasted a 295 pvp piece thinking it wouldn't contribute to the completion but luckily it did.)
This is just a side note for those having issues getting the 280 to swap to 295 after having 4 quests done ^like above. One thing that helped the swap that I had to do as well was to clear up to the next piece in stormsong (so just go do the 2 quest chapters so I had that first azerite quest as well). That quest showed as 295 right away when I got it, then abandoning the 2nd tiragarde quest and relogging made the other show as 295. I'll be honest, I didn't relog before this point so I can't be sure it was the relog, or getting that next azerite quest in my log that pushed it to swap over.
I'll try to give a breakdown in an easier to read format for those looking at a glance
Here's my zone order:
Drustvar (Chapters completed 1-7)
1: 280
2: 280
*Dungeon quest completed here.
(Scrolls Quest)
295
(This one I feel is irrelevant,i'v never had it under 295 even when it was the first thing I did)
Tiragarde sound (first half, chapters completed: 1-2, and 7)
3: 280
*Dungeon quest completed here
PvP War Campaign:
4: 280
Stormsong Valley (first half, chapters completed: 1-2)
5: 295
Tiragarde sound (second half, Chapters completed: 1-4, and 7)
6: 295
Stormsong Valley (second half, chapters completed: 1-4)
7: 295
(My neck level was 11 during this, for those that might want that info)
Hope this helps those looking to get certain traits and plan accordingly.
