You know, this weekend was the fist time it felt like drudgery for me, too.
Now, I normally play Perilous almost exclusively these days. I'd say my stats are average - not too low because I can play very comfortably, but not astronomical like a lot of people here who really grinded it out. I have end-level gear and armor, but not the highest of highs (none of the Hakkon weapons, for example). So, I mean, I'm in a place where 10 Perilous matches should be a breeze.
And they largely were, but there was no FUN in it anymore. I say this because this weekend has to be the most God-awful lag and latency I have ever experienced on PS4. It was fine for the original three factions, mostly, but Qunari came up a lot and it was almost unplayable. The first 4 zones breezed by, no problem, and then everything would go to hell on Zone 5. Had a team that had not failed a match yet, then suddenly wiped within 30 seconds. Not sure how their end was, but mine saw hitting buttons only to seemingly not have them register, so I'd be stuck half-way casting Firestorm but not actually casting it, for example. Or I'd put distance between me and an enemy, only to suddenly rubber-band back with almost no health left. Wipe.
Then next match came up Perilous Storm Dragon and it was one of those matches where no matter what you do or where you go, the dragon has decided all the electricity bombs belong to you. 
All this was happening right when I needed only one more match to be done. My buddy SilveSmurf messages me to join him, and I told him I was about ready to rage-quit. He convinces me to come over for one match, so I do. I then proceed to enjoy more of the lovely uber-latency that apparently double XP weekend brings, get teabagged once because that's what friends do in our circle and usually it's funny and good sport - although for once, it didn't feel as funny because the death came in a confusing no-one-hit-me-went-from-full-health-to-dead-instantly-what-just-happened manner - and I left shortly after getting that 10th Perilous done.
Sadly, I think I'm pretty much done with this game. It just wasn't fun. At all. Just felt more like a chore, something I had to get out of the way before I could go play something more fun/less buggy. And the lag was not my own Internet connection, which I know for a fact because I loaded up ESO after rage-quitting DAIMP yesterday and I had not one issue, bug, or lag-spot whatsoever.
It's like the complete opposite feeling I had for ME3MP. I was incredibly sad when those weekend challenges ended and I completed every single one (save for the first few because they weren't available for PS3, although I still performed the tasks anyway just as an "in spirit" thing). With DAIMP, I'm almost looking forward to when they end so I don't feel compelled to do them anymore (and I've completed every single one since they started). It's frustrating and sad because it shouldn't be that way.
