I know its the beta and a lot of material is unreleased. but to be perfectly clear:
there are NOT enough frigates//the frigates are not powerful enough to warrant much attention in the beta. most of the time I almost completely ignore them. the kodiac frigate (nearly the only frigate worth noticing) is far too high up on the research chart to look at with a forward eye, so I'm just gonna say this straight out
we need a better and more viable frig in the beta. otherwise theres little point to constructing frigs (well, excluding some scout swarms)
