I don't have the previous codex with me but didn't Lucius have a rule where he got more attacks for facing a higher WS foe and less for facing a lower WS foe on the basis he couldn't be bothered fighting them (something like his attacks stat was half their WS or he got +1 attack for WS 6 or more and -1 attack for WS 3 or less). That type of rule seems much more appropriate for him, or am I thinking of someone else?
