I would love to see it. For some reason KAM is some kind of sacred cow to CG and always has been. I really don't understand it since KAM is by no means a roster-changing character. He's got some great utility and ranks as one of the better Jedi but he's certainly not a game changer and (thankfully) isn't required for anything.
I don't think your comparison works though. This is more on par with farming Mal/Nego with GET2 or Hoda/Wampa with GET1. I've just come to accept that GET3 isn't going to be a thing for me until I get KAM at 7*. It was the same story with the other toons I mentioned. I do think the KAM shards are priced too high for GET3 - but I don't see CG changing that. I'm honestly not sure why they value KAM so highly. If you weren't in a KAM focused guild before RotE came along, he's now harder to get than a GL - and arguably harder to get than Reva - all while giving you far less return on your investment.
