So I'm sure other people have already mentioned this but, The Queenswalk portion of the Last Wish raid is currently bugged out like crazy. When someone gets sent in by the heart, the heart ends up cycling through all players (including players already sent in) and will instantly kill people. It's currently near impossible to complete unless you get lucky. So I advise doing all encounters except for the queenswalk and hold onto your keys until this is fixed. Hopefully that is sooner rather than later especially since this is one of three raids that are available right now after BL.
