I really doubt that. Think of all the ways casters can render a unit ineffective. Predictamancers see the future and never miss, Thinkamancers can prolly stun, Carnies cheat. That's just the 3 groups present, assuming any of them attack.
Then what happens if casters cooperate? Even when not linked, their abilities can synergize to be better. Dittomancers double a Shockamancer's blasts, Healomancers keep everyone alive, ect.
Even if there is a moment of chaos at the start, the neutral bystanders are going to unite if there is a threat to their home, and that will be deadly.
You've repeated my precise point.
Stun, more stuns, repeated stuns, mind control, walls from a dirtomancer, Carnies completely changing a fundamental game rule, Abbey turning off fighting for a moment, healomancers bringing everyone back to full health, etc.
And then suddenly, all that crap is done, and guess what? The decrypted took negligible damage, perhaps as many as half of them are dusted. (Unlikely due to the double bonus from Parson and Wanda, and the stacking bonus, but I'm erring on the side of caution.) Artemis attacks once, 8 casters fall over dead. The other rush forward, every caster in Portal Park dies in one hit.
You say "That's wrong, because Parson was concerned for his survival against just a few attacking casters." Yes, because he is level 2, and is only one target that everyone would focus their attacks on. He would die immediately from anything. That is completely unrelated to 10-50 heavily boosted decrypted vs ... casters.Casters do not have meaningful combat stats, and the MK has no normal troops at all.
Parson is smart enough to prioritize attacks against anything that can summon a combat unit.
