@ Cruiser idea
A "heavy" cruiser for high-tech is the route I would like to see, as the high-mobility option is already available in the Aurora and even Odyssey. High-tech doctrine is hit-and-run but having an anvil in the fleet would be kind of interesting to rally around. You really don't have anything like it until you get to the Paragon.
A heavy cruiser with a single, turreted Large Energy (centrally located, with say a forward-facing 240 degree arc with obvious blind spot in the rear) with 2 forward/center medium energy turrets, 2 side-covering synergy turrets, 1 medium energy turret in the rear, and 6 small energy around the exterior for overall coverage (high-tech seems to have a doctrine of 360 degree coverage). I envision it as if the Medusa was up-scaled into a Cruiser and had a central firing platform in the form of the Large Energy.
Mobility-wise, it's a little pondering (55 max speed) but has good acceleration and rotation, i.e. surprisingly hard to flank. Like the Paragon, it has built-in ITU (and/or, maybe IPDAI for all these burst pd changes?) but can't take Safety Overrides. Shields are top-notch (.7 like Apogee) and capacity is excellent (even for a high-tech ship) but dissipation is a hair below the Aurora. (Something like 12000 capacity, 750 dissipation).
The system is the lynch-pin, of course. High Energy Focus could be an easy drop-in for a brawling-type of ship, however, a proper anvil needs a defensive system. Fortress Shield would make this ship a mini-Paragon but I think we can be more creative. I'm thinking of a more active shield "absorb" that is active for a few seconds and completely negates incoming hard flux (doesn't affect soft flux, though!) but allows this ship to continue firing. I don't know if the AI could handle flickering this kind of system intelligently but even if used only as a last-resort, it would make fighting this kind of like fighting a Mora where they're difficult to take down. For the player, judicious use would allow this ship to take alpha-strikes, time torpedo/sabot hits, etc. Not necessarily a twitch-reflex system but definitely improves with skill.
Overall, it would hit decently hard and be be difficult to take down but compared to say, an Aurora, it wouldn't have the ability to disengage at will. It wouldn't be a high-tech Dominator, per se, but that would be the closest comparison. I also can't get the name "Minotaur" out of my head.
