yes, they dominate when you have the orc-chapter upgrade
Before that, they may be ok, but the losses are not exactly in line.Low level treants are too easily destroyed. And while I agree they may have been avtad overpowered before, after the change they lost too much.
Even now, I have squads of treants ll getting gobbled up by cerberus units, and thats in the freaking GZ zone. That just isnt right.
Part of that is because losses in numbers dont balance out with the damage dealt. A squad of 100 cerberus units does x damage, but if that squad is reduced to only 5 units they dont do 5% but still do 50% of a full squads damage. A completely idiotic system of course.
