This is when it’s useful to use a named character as your general: Archaon. Otherwise, always take an unnamed one. Only reason for Archaon is that he lets ALL heroes use command abilities without paying for them. That’s worth giving up a trait in my book. Especially in something like a BoK army with the heroes who can use ability for extra attacks. I don’t know if any other heroes do that, but if it’s something THAT good, take it.
Note: worthless ability combined with
KoS ability or similar abilities that don’t go off during hero phase.
I kind of want to edit this: Archaon’s ability isn’t even that good, since most of the better abilities go off in the combat/charge phase. You get a few in the hero phase, but a lot of abilities have branched out and take place in other phases. So Archaon, despite now being my biggest and coolest model is simply a paperweight for the moment. As soon as that book hits though...I expect big changes!
