For my rank as Commander, I see the two best Quantum torpedoes are as follows
a blue Mark VI Acc,Dmg
299 DPS on description, 10% Accuracy
a purple Mark V Acc,Dmgx2
294 DPS on description, 10% Accuracy
uses rare data samples
Judging just by the description the blue one shows better DPS so why would anyone bother crafting the purple? Is it because the blue needs dilithiums to buy the unreplicateables so thats why it has better stats? Does the modifiers factor into the description?
