for me, the traits of a leader would be: a sharp wit a silver tongue and a proactive attitude a leader would need these traits because of the rising difficulty of the crisis may call for a much quicker brain to process and lead, whilst needing a silver tongue to coerce and convey the message to his members, or if that does not work then his proactive attitude would finish it. i think that a good leader would be able to recruit and properly use his team members' abilities to its fullest, while recognising how to rid the group of freeloaders/ dead weight.
