I don't think we need this for delve or AA fights. I like WKRs the way they are now for the very reasons you just mentioned, but we already have adjustable difficulty settings for AA, and the ability to enter delve with six people now. I'm sorry if you're having issues with people sabotaging your runs, but I'm seeing even the most casual of linkshells on our server getting these clears. I've personally joined pickup groups for Morimar and Forret, and AA fights on normal or difficult (not VD) and been successful. Pickup groups are often more challenging, but I think until we have new end game content that's harder, Delve and AA provide enough of a challenge where you have to stay on your toes, but aren't so impossible that casual players can't clear them with some practice.
