It's also a 250 munitions ability, so it's perfectly fair that it can deal 30-40% damage to the sturdiest of Allied tanks. That is its purpose. There are multiple similar abilities, for the Allies too, that deal just as much or even more damage to even more sturdy vehicles for a lower munitions cost.
Fair, yes since everyone gets them. Is it fun? Personally i don't think so. I'd rather all of the loiters be gone in coh3 (besides recon). Or at least make them less impactful
Could be just me though. I understand the rage behind these abilities, but when people pick one to rant on and ignore the others there's clearly something else going on
