My enjoyment has suffered quite a bit from this update, but not completely due to the scaling. Scaling for the most part hasn't been noticeable to me unless I play my main right after/before playing my lower alt - then I am bothered because things honestly don't seem any different. I feel like it should be much easier for her, but it isn't. So in this case my feeling of progression is suffering with my lower characters and I care less about levelling.
But it is other aspects of this update that have made me play less. Specifically:
1. Dolmens. They were one of my favorite things, especially solo or with just a couple of people, but now they are being farmed by loads of players, presumably for daily quests. I was trying to get one done just to clear a zone and there were about 15 people there every time it spawned. I barely get to hit anything and it is downright boring now.
2. Delves. Often completely cleared because there are a lot of people now. But in the occasional one that isn't cleared (I sometimes hang out and wait for things to respawn) there are always still 2-4 people camping the boss. So again, hardly get to hit it (if at all) before it dies, and it dies almost immediately after respawning so sometimes there is a bit of waiting around.
3. Writs. I had left two characters at 9/10 crafting just to get surveys in Craglorn. Since the update I haven't even had one in Craglorn on any character. I also find the surveys rather rare so I'm just ending up with a bunch of mid-level materials I have absolutely no use for... they should at least give you the mat type you used to complete the writ.
4. Rawl'kha. Other cities are probably bad too (I have avoided Mournhold) but this is where an alt is currently stuck questing so I can't avoid it. There are so many people that today my game crashed after I teleported there. When it doesn't crash, the people stay black and don't load for ages. I wish they could find a way to partially instance it or something because there are way too many people there.
I had the day off today and thought I would spend a decent amount of time playing, but I got disheartened by not being able to enjoy any dolmens and delves and then trying to deal with Rawl'kha was sort of the last straw. I hope the boss camping settles down once people attain whatever gear they are trying to get, but I don't have much hope for the dolmens. Those really should not be a daily quest.
