Well I finally completed the 100 Exalted reputations on the 9th of March (9/3/2021) and I never actually noticed until I used a bunch of medallions to get the Sha’tari Defenders rep up to exalted and noticed that I didn’t get the achievement notification.
I checked and saw that I got the achievement 9/3/21. The only thing I can think of is that getting the Stitchmasters rep to Exalted was counted but not at the time I got the rep up.
Anyway, I am happy to get the title and mount.
YAY grats! I really want that mount, but I’m lazy with older reps. lol
I was really confused when I got that achievement this expansion.
I have one toon with 98 exalted reps… but it’s not this one that I’m playing.
Apparently it’s now account wide and shares reps.
(At some point I’m going to get the rest of the reps on the other one too.)
Congrats. Enjoy the mount.
Grats! I just finished Ogri’la a few days ago and I think at 97/98. Soon!
Congrats OP!! 
Congratulations!
Motivated to go do this myself now.
Big congrats and good job! Enjoy your new beautiful mount and title.
i did it over 2 years ago when there were a lot less reps…
a lot of the older reps are super easy to knock out quickly now, or can just be purchased.
(totally not salty that i spent time playing the game instead of just buying my way to rewards) 
Congrats! That’s a lot of work
Congrats Eritole and welcome to the club. 
I need to get back to work on this.
Grats! It’s such a pretty mount. 
Gratz
Thanks for reminding me of yet another area I’m slacking off in.
Oh I’m sure. I’m just lazy.
Congrats!
working on my 2nd and 3rd characters with that achivement. My hunter has it done now I am doing my dk and warlock.
Are your characters on different accounts because I don’t understand why you would need to do it again as the mount and title are account wide.
And forgive me as I don’t mean to be rude. When I finally completed that I was so thankful that it was done.
Huge grats! I wrapped this up back in bfa, and was so glad to be done with it. Enjoy your new beautiful pony [and so nice they added flying for these models on top of it]!
