Is there a good way to find PUGed raids aside from duty finder?

You don't queue for EX and beyond.
Use Party Finder.
Another option is to join fellowship that farms older EX and find a group/discord from there.
These can be viewed in the Social Tab from the main menu.

In your opinion, how many 80s are necessary to do Wreath Ex Unsynced? Do you still need to do the tank swap mechanic (so 2 tanks still)?
