I mean, how do you critique "pulled out of hat stats"?
Given that the real world purpose of any of these designs would be to assist in generating conflict as part of an interesting television program or book or what-have-you, and also on how well they fuel fanboy angst, then you could maybe critique them on how well they facilitate those ends.
Of course, by that standard, the designs presented so far as horrible, as they are waaaay too well thought out and reliable. So I present, for your consideration, the 2250-era
U.S.S. Incorrigible, NCC-00412-W:
WEAPONS: Phasers and Transphasic Torpedoes.
The launchers have a tendency to stick, resulting in live, armed torpedoes being stuck in the launch tube. They have to be disarmed in time, or the ship could be destroyed. The ship has as many phaser banks as are needed for the plot at any given moment, even if that means that in special effects shots they are shown as emitting from shuttlebays or the deflector dish.
DEFENSES: Shields divert energy blasts that they are struck with to surge supressors located in consoles throughout the ship, but mostly to the ones on the bridge. Said supressors are never quite enough to entirely supress the energy, which results in them exploding, knocking the crewperson manning the console to the ground, burning or outright killing them if necessary for the plot.
On occasion, energy is redirected to hydraulic panels under each deck that wildly move the surface of the deck around to one side or the other.
CLOAKING DEVICE: Cloaking device hides the ship from detection in every energy range except the visual. Ship can fire while cloaked by pushing torpedoes out of a cargo bay manually - if they can get one unstuck from the launch tube to take to the cargo bay.
PROPULSION: Improbability Drive.
ENGINEERING: Every use of a replicator on the ship results in a very tiny but not statistically insignificant chance of an immediate antimatter containment failure.
APPEARANCE: Ship looks like a Connie-refit built with post-Dominion War parts, except for the addition of a large, turtle-shell-like compartment between the warp nacelles - nacelles that are bent outward at the front for no apparent reason.
The shell contains "Sub-Omega Particulates" that supposedly make the warp engines run "smoother" - but in actuality, the addition of the shape makes the ship look like the pictograph for a particularly obscene insult in the written language of a race the Federation hasn't encountered before - the one that kicked the butts of the Borg, Species 8472, and the Dominion on the way here....
Aneas - feel free to sketch out the
Incorrigible, if you'd like.
