I also think Dominators have the potential to get another boost this version by staking the +50% and +75% maneuverability unlocks (on top of the usual skill). Add thrusters and I imagine the things can spin like tops now (haven't tested yet).
It does.
The main benefit of stacking both perks is you do not need to spend lots of OP for Auxiliary Thrusters anymore if the ship turns fast enough. For example, I used to always put Auxiliary Thrusters on an Odyssey. Now, with both perks, it turns fast enough that I no longer need the hullmod, and I can spend 30 or 35 more OP on better weapons.
It is like getting ITU for bigger ships, you save OP by getting ITU instead of DTC.
However, battleships still benefit from both Auxiliary Thrusters and +125% maneuverability from both perks. If you want to solo fleets with a battleship, being able to turn fast enough to face fast frigates like Hounds and Tempests is good.
Re: HyperionWhat makes the Hyperion so good, at least as a playership, is it can bypass enemy shields very easily. See a nasty enemy ship with tough shields? Teleport where there are no shields (or back off until it drops shields, then teleport), fire (mining or heavy) blasters, then teleport away, vent, repeat. In 0.65, it could solo nearly every fleet. In 0.7+, Hardened Subsystems does not slow down CR decay as much, so it probably cannot solo as much as it used to.
