Why are Talyn drop chances so low compared to other armaments?

[Benasist]

After farming for a long time and not getting a single Talyn, I decided to look at the drop table to see their rarity. Then I realized that wreckages from Orm Crewships have a 1.29% chance to contain a Zetki Talyn and a 0.52% chance from Orm and Vorac Weavers. These chances seem a bit too absurd, especially when the other corpus armaments have 30% chances to drop.

There are items in this game with actual 0.0066% drop rates.  They want everything to take forever and the only grind system they understand is pure, unmitigated RNG.

You need to consider drop chance against enemy density. The problem here is that it's a super low drop chance with an enemy you only get a few of per mission, in specific missions.
