I'm currently in the process of rebalancing all of the nomads ships with thorough playtesting, so hopefully folks won't find them so OP. I have noticed so far that the Scarab fighter is incredibly OP, so he's getting a solid nerf. The Iguana was actually underpowered so I will be giving them a boost but also increasing their cost; their fleet cost and base value will put them squarely near the top of the list of the heaviest fighters, which was actually my intent; somewhere between frigate and fighter, which is good. The Komodo was overpriced I found compared to similar cost destroyers, and so I'll probably be just reducing their fleet points etc.
As for the Doom Cannon: I will be reducing the firing rate and upping the flux cost per shot, given that it has no limits on ammunition, and to reinforce the idea that the Gila Monster requires support to be successful.
@megal00t: I strongly oppose making big balance changes like what you've described without my permission. Please remove Nomads from your pack, or keep them in as I have made them. If you have suggestions, please PM me.
