Long time fan, but some things are really infuriating in SV and with the new quests from 1.5 more so than ever.
Your character randomly turning elsewhere when using swords or other tools, still not fixed.
Some quests make zero sense. Robin wants 80 Hardwood... cool, ok. Why do I have to GATHER it!? Some of the quests really could've used more thought and common sense. It is absolutely insensible to make them this way. And ofc, the quest description says nothing about it. Just "robin needs 80 hardwood", well cool. So either work on the wording or think about how and why you wanna make quests absolutely, infuriatingly stupid.
That being said, I appreciate the huge content update, but sometimes it seems like there is zero thought given to some things because if you play the game normally, you end up doing things out of order (how some quests would like themselves to be done) by default, and hence ruining some quests. So quests essentially catch you off guard by assuming you are way, way slower than you actually are. This is really, really infuriating and shouldn't be the case. Just let me hand in my damn wood or whatever.
There are quests where it makes 100% sense, like the Albacore quest for Demitrius, but there are quests like Robin's where it is just stupid.
Edit: The RNG paired with limited timed quests is a joke. Seriously, we didn't get ONE prismatic slime so far in multiplayer (2) and went religiously about it. This is horrible and imo, overall, the new quests are largely extremely badly balanced and should be reworked. They are just stupidly grindy and insensibly designed, not "challenging". And yes, we used strategies like double dipping and working on different floors to increase the ground we can cover. Essentially we covered about 15-20 levels per day per person, ranging anywhere between 60-80 floors per person, totalling to 120-160 in total so far. Reading what others experienced... this is another good example of how horrible some of the quests are.
