I am assuming you didn’t do Kara in Legion when it first launched either, did ya? Because the difficulty is very comparable. Its a mega dungeon Rastlin, come on.
The dungeon was pretty easy if you actually pay attention to and actually do the mechanics.
Then again, it somehow takes you 7 hours to do Nazjatar and Mechagon dailies… so… It might just be out of your skill range in general I suppose. /shrug
for reference – 7 Hours to finish the dailies!
