Why do corvettes give so little xp?

Lets compare Acolyte corvette and Disciple vessel: Disciple gives 32xp with fleet slots of 4 (250credit 40m 0c), while Acolyte gives only 8xp with fleet slots of 3 (175credit 15m 15c).

Every other combat ship gives xp proportionally to fleet slots or cost somehow, so why would corvettes give almost no xp? Right now in multiplayer you could just suicide 100 corvettes and capital ship in the same well only gains 800xp while losing lets say 50 Disciples gives 1600xp, this cant be correct can it?

Sure corvettes have alot less hull points but due to fast moving after firing weapons they wont get hit much anyway and will survive a lot longer if they would stay still.
