They have been tested. These specific ones slightly less, but they're intended to have a high tactics dependence from the design, thus why the long-range missiles are disabled (this is by design), and I guess, turn out to be rather punishing for an incorrect strategy because of it. Identifying the correct strategy should make it simple (if not trivial)... I let my testers play it a few times and they figured it out relatively quickly (one or two re-tries) once they noticed what were the threats and how to address them with the tools presented/options available.
However, I will address this with a patch to make it easier if you so desire.
or I'll just take the easy way out and let people take long range missiles and go whee there is no need to even think let's just spam
