you probably didn't try Chaos summoning line.
Pit beasts are nice. They get promotions and stay an extra turn if they get a kill. On the other hand, chaos marauders suck (str4, move1, can turn against you... yawn). My experience with them comes via: Keelyn, Bals, writing\festivals\mystic\hunting\Honor\Hidden\Commune: Druids + Summoner Trait with Chaos, Mind, and Nature mana.
When tactically employable (I mean, you can get your target onto a desert tile via whirlwind or a limited approach lane) Sun pwns all.
In general, Law is prob the best. But this is a tangent discussion.
-----
Pit beasts do not compare to meteors and tier 2 summons do not compare to fireballs - especially without the summoning trait. Besides, getting a Summoner (tier 3, as opposed to conjurer tier 2) requires
more beakers than Strength of Will. Costs more, rocks less. At least Summoning (the tech) costs about the same as sorcery. Costs same, rocks less.
IMHO, nothing compares to the overall usefullness and unstoppability of fire. And I'm a guy who uses pit beasts, domination, and taskmasters to take cities because using fire is simply below me
