Damascus strategy is awesome! I'll definitely give it a try. I only use 4 comps, 18 archs and rest pike. I drop the comps near the catapults and the pikes near the ballistas and that's been my strategy ever since. I do lost some comps from time to time but I don't bother the time to make them. I only hate having to build almost all archs and pikes because of some well placed or poorly attacked catapult.
That's why I'm gonna try the 10 comps. I think they'll be able to wreck the ballistas so quickly that none will be killed. And then they can take care of the rest.
By the way, I think pikemen are not that useful in this strategy because after the comps are finished with defenses they still have a pretty good DPS and can take other buildings pretty fast.
Well, I'll see what will work best for me.
