As the title asks, are mercenaries a viable faction without temporary alliance (either adding mercs to imps or rebels to mercs).
My buddies and I have run several different merc only lists and have found that they are generally lacking. It's not that their units are bad or over pointed, it just seems like there is not enough "support" and synergy in the list.
It seems that a well played/balanced rebel or imperial list will often trump merc only lists as they are very one dimensional in their play.
If anyone can offer suggestions as to what we are doing wrong or ways to improve our merc playing, I'm all ears. It's something I would really like to figure out as I enjoy playing the underdog.
