Levelling the Psijic guild quest line as it is on PTS is in my opinion the absolute worst kind of MMO quest - go to these 9 places and press X. Now do this 5 more times.
That's it, that's all you do, and I have to say that is an incredibly brain-numbingly dull and boring grind to do on even one character! I have been praising ZOS all this time for coming up with good Elder-Scrolls RPG style quest designs that makes people interested in listening to dialogue and reading books while playing the game, but Psijic levelling harkens back to the release state of ESO.
In comparison, levelling the Thieves Guild and Dark Brotherhood guild quest lines was actually interesting for a thief or assassin to do, you had to steal things, or kill people. This is actually involving gameplay compared to the Psijic Guild!
My suggestion is to add time-shifted monsters to the time rifts. Reduce the amount of breaches to like, 3-5 per quest to keep the grind time the same, but have the player fight waves of random time-displaced enemies at each breach. We could have things like Oblivion guards leaving the breach saying "HALT! YOU HAVE VIOLATED THE LAW!" or just whatever monster models you have at hand (there's plenty of models you can use ingame, sand gargoyles, Haj Mota, vampires, anything you can think of really). Lore-wise these monsters could have become insane and can't be reasoned with, give them a line or two of dialogue as well for flavour purposes to indicate this.
Maybe physically time-travelling monsters aren't lore friendly, so have them be ghostly echoes instead, and give them a ghost effect. Run this by the Loremaster if not sure.
What do you guys think?
