I've been looking through this set of Homebrew, and it looks incredibly awesome! There where some questions I had that I couldn't find the answer too though, so I hope someone more familiar with it could help me answer those.
First, a general impression I got was that energy seems very restrictive. Using higher level maneuvers and/or being engaged in airborne or space fights means you could conceivably burn through your entire energy reserve in 1-2 turns, and then you'd be stuck waiting for a 5 energy per turn recharge. Is that correct, or did I just fail to find all the energy and energy regen increasing equipment, feats and class features?
Secondly, how do feats interact with vehicles, such as mechs or battleships? I get how many of the basic feats like weapon finesse work, but would I be able to apply, for example, the flyby attack feat while piloting a mech or battleship. What about feats that increase flight maneuverability?
Speaking of battleships (I might ever so slightly be falling in love with the ship captain class), does flying the battleship consume energy as it does with mechs? And can you do a full-round attack with those twin-linked missiles (for, for example, 4 12d8 missiles at level 12)?
Lastly, I assume the attack bonuses listed with weapons is on top of everything else? So, to give an example, a lvl 12 ship captain firing the missiles from a huge battleship would have an attack bonus of 6(BaB)+2 (weapon bonus)-2(size penalty) for a total of 6?
regarding Ammo weapons, am I correct in understanding you can fire them as many times as they have ammo, and then you need to spend a full-round action to reload the weapon?
