Because they are all alieny and cool and different, AND they have a massive ball of energy at their core, howabout instead of just the usual ship explosion and frigate debris afterwards, this happens;
The ship stops, like it’s dead, then the core flickers, then a massive green explosion like the phaser one happens and the hunter is left intact, just as a debris object, with none of the green animations showing. essentially like a hunter that got turned off. :3
It would look so cool imho and would add a bit more depth to the game. The explosion could do considerable EM damage to all ships in a small radius.
Aka, too lazy to create a new animation because every ship currently uses the same one Maybe they are too busy with dreadnoughts. That would be a better reason
