Tartarians are so cool that increasing the cost would be a coolness factor reduction.

QM is totally into coolness factor. It's really not hard to comprehend the changes in CBM if you use the coolness ration. For example, Jomon archers are uncool so they get nerfed. Androphag archers, while cool, are bugged so get nerfed.

Devala are cool so they get buffed. Armless dom spreading prophets for pearls are way cool.

Kydnides are cool so get cost reduction.

Dragon master is super coolio so gets cost reduction.

I don't know why you guys spend so much time debating QM's motivation. It's simple. It's the cool factor.
