crushing charge is a 10 nora ability and also beasts are way more splash-able and available then zombies
I find it balanced in theory, as it's not permanent and doesn't give crushing charge. Also I've seen a game yesterday with a certain group of undead firking some champions up, so I'm not sure this is a totally random thread. And Burns, SL doesn't have beast herder so I'm not sure what you meant with your first post.
I'll tag along and say that you know that SL beasts' problem isn't not having beast herder, but the lack of alt damage and Skeez Herder being expensive.
