I don't think the "Let's add another GMS exclusive" is a good train of thought. Why wouldn't you advocate this be added to both KMS and GMS?
This change would benefit both versions of the game the same. It would be a good change for all regions that have reboot.
Reboot might not be popular in Korea, but it still exists and there are still people who play it. Why would you exclude them?
Nexon seems to be going for more 1:1 features anyway, so I think moving forward asking for anything to be added to GMS exclusively hurts your odds.
Maybe I phrased it poorly, I don't mean to exclude KMS from getting Zero. I say it more as a counterpoint to the "if it doesn't exist in KMS, it can't exist here" mentality. Of course it would be great if KMS could get this feature too (partially because it would guarantee it for us), but I feel like pleading for changes in KMS on the GMS request forums is about as effective as trying to yell the suggestion across the ocean to them. And I'm glad I missed the other times they were accidentally able to be created in Reboot, my heart can only break so many times.
So the other, 2yr old, thread pleading for the Zero class to come to Reboot was locked for seemingly no reason after being bumped. The last acknowledgement I remember hearing about the topic was a MapleFest Q&A session where the response was "we'll look into it." And remembering the one time they accidentally allowed Zero to be made before wiping them in a soon-after maintenance, so it appears to be possible.
To be honest, I'm mostly just looking for a direct answer of if it's even being considered at the moment or not. I have friends that have quit the game but acknowledge that they would 100% return for Zero to be released. I'm enjoying the game right now but the needlessly exclusive class was so much fun to me when I played a regular server.
Before "KMS doesn't have so no" - we still have SW gear, Gollux, Kanna, Hayato, Beast Tamer, and Frenzy/Fury totem. We're not 100% in KMS footsteps and I just want this to be another exception.
