I've only hit Exalted with Scryer on 4 (out of 5) of my characters. I *was* farming Mech & Botanica dozens of times a day, mostly Mech (for the Totem of the Void) so I was getting a metric-fuk-ton of Scryer rep items. It didn't take long to hit Exalted. But since hitting Exalted with Sha'tar I've stopped farming any TK instances thus I've still got one character in need of her last 5000~ rep.

Hitting Exalted with Shattered Sun was rather unexpected and came up on my rather quickly. I was doing my dailies and just happened to glance at my rep, I thought it was somewhere between Honored - Revered, but to my surprise I was about 8-10 bubbles from Exalted. So I decided to run Magisters Tce to the first boss and rinse and repeat. It only took 12-13 times to get the rep I needed. There are only 8 pulls between you and the first boss, its an easy shard run!
