Some things I've noticed:
1) Colossus really needs more OP. The Phaeton, a destroyer-sized tanker, has a fair bit more than it despite the Colossus being a cruiser! They both have 4 small ballistic slots too so it's not like the Phaeton needs more OP for having more weapons...
2) The 25% fuel reduction perk doesn't update the relevant ship info tooltip.
3) The Hammer Barrage only has 20 ammo? The Cyclone also has 20 ammo! HB only gets 5 volleys @ 6000 dmg potential VS. Cyclone's 10 volleys @ 8000 damage potential. Yes the Cyclone is 6 OP more expensive but I think the HB could at least come with 2 or so more volleys (so 28 ammo or something).
4) Could anyone please explain it like I'm 5 and tell me why you'd take Carrier Command over Fighter Doctrine? Is Fighter Doctrine the obvious first choice and you'd only take Carrier Command if you intend to pilot a carrier...? Do they stack for you if you're piloting a carrier or what?
5) If an item is forbidden to trade at the market screen, you can't pick it up to rearrange it in your inventory. Very minor issue obviously but it's annoying to those who are inventory neat freaks...like me!
