What level?
Exactly this.
So I just ran 2 dungeons to get some sample numbers. Level 73, full rested XP. No XP buffs like DMF. 25% bonus XP from having 5 80s.
TW Utgarde Keep (bonus from Finder: 97,800)
- Mobs: 10,006
- Bonus: 123,538
- Total: 133,544
TWW Rookery (bonus from Finder: 65,200)
- Mobs: 114,180 (I dinged 74 near the end)
- Bonus: 94,385
- Total: 208,565 (note: this would probably include higher bonus XP because I levelled)
So this is an imperfect comparison but any comparison is going to be imperfect because it depends on what dungeons you get but the TWW dungeon gives 56% more XP because of the mob XP.
So there’s currently ZERO reason to do TW dungeons other than the weeklies. GJ Blizzard.
