I think the balance of explosive damage vs the Hwacha Puts the Artemis in its appropriate place with regards to outright kills, since it fires single projectiles.
To give an actual example of my own view of the Artemis and its slight OP, I get hit in the bow and my engines get destroyed. I think the AoE radius should be decreased to prevent it from functioning as powerfully as a Hwacha in terms of a disabling weapon. That would make the fly-by disabling more difficult, but still give a ship that's been stably positioned the chance to utilize its full potential. Alternately, it would require loading of burst to reclaim the power of the current AoE.
That's all pretty preemptive though. Once we start seeing all-Artemis ships being the meta (which I think we will come close to), it's a fair call to ask for change. If Muse is too proactive, the game gets into a balancing PIO where unnecessary changes are made. I think the playerbase, to include the more casual players, has to adapt first before an acute and accurate assessment can be made.
EDIT: Meaning I think just a week might be too fast. But then again, I've also abandoned most guns for the Artemis, so perhaps it's not.
