Utterly crap.
Seriously they are a joke. Their tactic cards have far too little pay of for a large investment to achieve, compared to other faction cards they are out of sync.
The main heavy hitter in the faction can be easily countrered by simple not attacking it, as it will do 2-4 wounds when it attacks... which can be easily healed by either a Tactic Card or a place on the political track... also it costs 7pts, 7pts for 2-4 wounds is simply laughable. On the flip side the same model can be removed far too easily without getting to do anything. The Savage Giant, incase anyone was wondering which model I was on about. I see wat CMON aimed for with the rules for this monster. However it simply doesn't work, in all my 30 years of gaming I have never encountered a unit that can be countered by simply not attacking it.
For the record I play mainly against Stark, and Nightswatch, so the panic shenanigans that are all to common with the Freefolk do very little. Both factions can hit a lot harder than the Freefolk can, and can tank against me very easily. Oh, and they can take Neutrals, which again not having access to limits the Freefolk, sure it makes sense thematically, however give the Freefolk something to make up for this handicap.
In all honesty, I started with Freefolk, but I may just quit this game, which is a shame as the core mechanics are fantastic. However the gaming experience is ruined by the Tactic Cards. They are nowhere near balanced, just go look at the Freefolk ones and the Nightswatch ones. I once had a game where it was advantagous to attack Ghost with a unit of trappers, I caused 1 wound due to his power armour save. The Nightswatch player had a card that then allowed a nearby unit to heal 3 wounds because I attacked his unit. Which meant a Tracker returned to a nearby unit. So my attack rewarded my opponet more than it did anything for me. This has so far been my experiance with the Tactic Cards.
I wish I wasn't so negetive about the game/Freefolk, as the core system is very nice, but starting with the Freefolk has put me off, I think I've managed to win 1 game, most games I lose by 8-10 victory points. Sure winning and losing aren't the aim of a game, but after a while getting kicked that badly on a regular basis makes the game not fun.
