KE certainly doesn't say everything, and I would say that building something that people use or bringing in a lot of new users count a lot more. I'm not quite sure if having assets in projects on Hive really count toward it, I have quite some Splinterlands assets myself but see them as completely different. Also, I think incoming delegations should count toward KE Ratio. In the end, it's by no means a perfect indicator but I guess it's the best thing we have right now.

Thanks for the suggestions !
