It's clearly not overpowered, in fact quite the contrary. The Irra is the only decent ship left for the nomads, more specifically it's guns. Nomad cruiser guns on human cruiser should never happen fyi.
However it should be, nomads will always be in lesser numbers than humans that are technically meant to stand together. This is why they effectively are an inexistant threat for everyone. You just see them like "yet another red" not "OH FFFFFFFF NOMADS CALL 911".
