Alright,
This one is a sister thread to Most Lethal ( [url]http://www.lounge.belloflostsouls.net/showthread.php?t=615[/url] ). For this one, let's hear your personal worst or least succesful unit. Not what you think is useless in the codex, but what unit in your collection has failed the most. Any particularily epic failures?
Mine is my Chaos Space Marine Daemon Prince.
He managed to deploy in the wrong area of the board (random deployment entries for each unit), ran towards a deep striking unit, who were destroyed before he got there, then turned around to try and kill some sisters (it was against a sister/IG force), but was then mauled by a group of 20 Repentia... Total kill count for him: 0 models. Games played with him: 7
