look at this replay :
or this one
first replay show orks has double more economie, but cant get the choas preds ; the pred with his lame economie can go 3rd age and the orks cant win...
the second replay show how an ork 3rd age cant get a chaos 2nd age with his predators...
and now the question is
is their not a problem with chaos predator vs orks ??? imbalance problem ? no solutions for orks ???
