Which one gives the best EXP for level 210? I heard the 200 dungeon has a bad, or decent? EXP, but I personally haven’t experienced both dungeons yet. Just need to remind you that there’s 20 level difference between my level and the 190 Dungeon.
Oh, do they drop anything other than Talt?
190 has 2 boxes and better xp. I grinded there until i was 215 
I questioned the 190 dungeon giving better xp than the 200 on my first character. I tested it for myself since I was skeptical and 190 dungeon is much better for exp. Queue times for the 200 dungeon are long since everyone just boss rushes the dungeon and the exp the dungeon gives isn’t that great even. Just stay at 190 for til around 212-214 and then get into grind parties if you want exp.
As far as items go the 190 drops the following:
Firelord Card
