"Your 'small, primitive ships' will be seen exiting from the cloaking fields of other ships AKA the federation easily becomes aware of the romulan cloack."
OR just release them in the many, MANY vast nebula that hide the ships from sensors (even MODERN sensors) and have them exit from there. The humans would have assumed they warped in, hid in the nebula and exited to attack. And again, those nebula are EVERYWHERE.
You think you're brilliant, but you're not interested in discussion. You don't debate, you argue, and I don't want to argue with you
