I personaly like to have overpowered flagship, if AI can have 20 alpha core officers in single fleet why I can't have something nice?
And for 90DP even wyvern nest with my "modifications" is not nearly as overpowered as it looks.
I removed 2 fighter bays and added 100 more OP for da guns, and reduced shield eficiency to 0.8(0.6 is bit to much), still it needs front shield and stabilised shields to even run shield generator and reduced maneuverability to 1/3 of original values.
Still as with any single ship it will fail if overrun and since all its dps is concentrated at the front fast foes can be tricky to deal with, ship has size of an spacestation so dodging anything is not an option forcing you to take good pd weapons on most small slots.
With 5 pulse lasers and expanded mags it was able to tear radiant apart while maxing its own flux, if there is more ships wyvern nest will overload or be forced to tank.
My "test sample" is typical pirate invasion fleet with capitals, wyvern nest dealt a lot(a lot) of damage but eventualy got overrun and died to missle spam(curse you ventures with pilums!).
Meanwhile GH onslaught from tahlan shipworks for 40DP was able to tear down whole fleet and lost only 80% of hp, mostly due to my bad piloting.
Paradusa and wyvern wing both have bit to much flux disipation in my opinion(500 less maybe?) but they are sufficiently slow and immobile to force them into tanking whole fleet at once and dying.
Epitomes have silly shield efficiency but considering DP cost even carrier with fortresshield(witch is pure troll mode btw) is not that op since it is to slow to kite anything and gets flooded with so many ships that its bombers are not able to survive it, with 0.6 shield eficiency they would be totaly balanced.
And they are designated as carriers and not battle_carriers, AI needs to know to get into battle and not stay away.
On the other hand there are ships like cathedral from SWP, hell this ship is realy OP with double layer shielding and infinite missle spam.
These are kind of ships that should be unique, perfect flagship but only one in the fleet.
And why you are suprised? those are good fricking ships!
