Does anyone want to champion them or are they just kind of meh?

I'm trying to be objective here, but I really am just fairly unimpressed with Frostlings the more I play them. Theocrat is maybe the one production class they synergize with due to crusader mammoths as well as witches and queens getting healing Inflict Frostbite is good but also situational and late (tier 4 RG), which, again, see above ice resistance on common enemy types.

Racial governance is fairly weak all synergies point to playing a caster, namely Sorc and Necro, which further makes any possible Warlord synergies fairly weak as there is nothing in Warlord/Dread that makes racial pikes better, and furthermore you usually just use those class units anyway.

Tier 3 support unit with no ranged attack is fairly painful even with guard break and damage boosting for frost weapons.

The Ice Witch has to move into a vulnerable melee situation, the White Witches are expensive and squishy, and Mammoths only deal physical damage and have poor defenses

Frost is also resisted by many of the same enemies as Blight, which is especially problematic with all the undead running around, and Frostlings only get a few options to deal with this, none of which are particularly great.

This means any non-caster Frostling player has to risk losses early at a critical stage in the game, which makes them much harder to snowball with Fire damage is also probably the most common elemental type to match up against and there is little you can do to mitigate this except by making expensive White Witches, again, which plays into a specific caster-style playstyle.

Magma Forges guarantee a fire damage matchup early and there is no way to mitigate unless one spawns with a White Witch, which isn't guaranteed, especially with Weak starting army.As the title of my post implies, I'm not particularly fond of the Frostlings.
