I'm still struggling to understand the equipment ratings, today I wanted to purchase a kill warrant scanner and in the station I was docked there were 2 types available, class A and class B. The difference in price was substantial and the class A had also a more than doubled power drain, however the scan time, range and health was exactly the same. So is there any reason to buy the more expensive and power hungry piece of equip? Are there other equipment stats we are not seeing?
