I do not believe this is "useless" per se. But mark it what you want it to be.
Step 1: Queue up for Random LFG.
Step 2: Join said LFG.
Step 3: Die instantly (pull maybe)
Step 4: Release spirit
Step 5: "You can not vote kick this player as he is not alive"
Step 6: ???
Step 7: profit.
Note: as I was the Griefer, I was unable to make sure 100% that you couldn't be vote kicked while dead/in spirit form, but hey.. I wasn't kicked and the group leader was screaming and shouting about how I couldn't be vote kicked. So, I just put 2 and 2 together. If someone can prove me wrong let me know, and I'll delete the post. But from what I can tell, this should work.
Enjoy!
