No more absurd than the Ent-D with a skeleton crew taking on the Borg ship from "Descent".
To me, it is. Much more absurd.
The Borg ship in "Descent" was a ship cobbled together by some rogue drones vs the flagship of the Federation. And yes, it had a smaller crew complement but that's all that's needed to control the battle functions of the ship, they didn't exactly need the stellar cartography and archaeology departments to be at 100% capacity to defeat it now did they? And the borg tactical cube was the absolute cutting edge in Borg technology vs a ship that wasn't made for battle and only had some now outdated Borg inside knowledge.
I just wonder what was going through your head when making the comparison and deciding both situations were equally "absurd".
