I have been thinking about building a new kind of undead army. Instead of the to-go units (soul reavers, wights and wraiths) I would like to capitalise on a strength of the undead army: the ability to field a lot of staying power/nerve and flood the board with them.
Other than using rev cav (still very resillient for their point costs, even with the clash '20 nerfs) of the units that can be used well in this context are zombie trolls. As it happens, I own three hordes of them.
The idea is to combine as much nerve and defense as possible with reasonable hitting power and surge tricks to flood the board with units that take some hitting power to kill. A baseline of revenant cavalry and zombie horde chaff supported by goreblights and zombie trolls.
The zombie troll should have been an ideal candidate for this kind of army. (it was more or less designed with the zombie troll option in mind) but in my playtests they fail more often than they succeed. While, on paper at least, they should do 6 damage to def 5+ and 7,5 damage to anything else, they bounce too often for my liking.
While 6 damage is a bit on the light side (needing a “10” to rout an average elite regiment) , they too often fail to do even that amount. As soon as terrain or ensnare enter the fray, their average damage drops to 4, which is neglible. Also, the 4+ to his is very swingy. I’ve had good rolls, but too often they underperform on that charge that I really want succesful.
I mainly chose this option (over soul reaver infantry troops which do the same damage at fewer points) because their defensive stats. It appears that -17 is not enough nerve to stick around when you need them. A normal cavalry regiment (16 attacks, TC 2) has a decent chance of routing them after a wound or two or when charging along a fighty hero.
In KoW2 they were 165 points (but def 4+), for that amount they were great. For that point cost, I could accept them fluffing their attacks on in a while. In KoW3, for 25 points more, not so much. They do not hold up when compared to Soul reaver infantry (who would?) or wights. Both these options are available to an undead general too, so that means my two hordes of zombie trolls in the list will probably be replaced.
Am I missing something or do I just need to accept that Z-trolls are not worth it, at least until the next Clash?
