The Artemis is far, far too efficient at killing ships for the amount of disable it puts out. It also does not require nearly as much skill to use as people claim. This doesn't mean that it requires *no* skill, but basically any player that flies and practices competitive can use an Artemis to roughly equivalent effectiveness. The fact that it's incredibly efficient at both disabling and killing chokes a great many ships out of the meta.
The Guns community has a warped view of "skill cap" when it comes to a lot of things, because Guns has a somewhat high skill floor, but many aspects have a low skill ceiling. In addition, a lot of the skill floor is simply based on a large amount of information to take in, rather than muscle memory or mechanical skill. Thus, we look at novices and claim anything they *can't* do requires skill, instead of comparing ourselves to people with competency, and trying to figure out what the exact differences between a "competent" Artemis gunner, and a "great" Artemis gunner.
(Edit: I understand Artemis is beloved by many high-level players, because it's a weapon that rewards proficiency, something that is relatively uncommon in GOI. Its arcs make it fun to play around with, and it fits into most ship build seamlessly. However, the fact that it does so much, so well, chokes a lot of other option out of viability. It doesn't have to be dominatingly over-powered to be unhealthy. As with the hwatcha, it is far easier to execute a mid-range Artemis based strategy than it is to execute one that counters it. The Hwatcha is a problem at all skill brackets, the Artemis is only a problem when you start reaching competency-level skill brackets. So yeah. Maybe attacking some sacred cows, here, and I'll be honest--I prefer brawler-meta to midrange. But everything is massively disable-focused now, and that's a problem.)
