That’s good, because if I was ever in a normal raid that wiped on any boss for any reason I’d leave immediately. It’s not hard, especially at the end of the tier, even if the players don’t have curve.
The reason why your argument fails here is because most pugs can’t work together and are incompatible, especially the more inexperienced groups. There are plenty of progression pug runs where the raid learns together slowly but surely, so you could join those as well. No need to join groups that are going in there expecting to one-shot everything because they’re only looking for players who meet certain requirements.
There are some groups there but majority don’t ask curve for normal. Btw those groups who asks curve for normal clear never gets full same as those groups who asks 1k for +6 dungeons. Just don’t bother with them. I can ask 1.5k rio for +6 freehold but it doesn’t mean people will join.
Btw i got my curve with pugs , you can check my rio page there is a link to my main there and you can clearly see the guild i’m in doesn’t have curve while i have it.
