Completionists love the grind, because to them, the grind is the challenge.
To be fair I see it more like love/hate relationship.
They cannot play in other way, than metagaming, they cannot play other way, than with the best gear, so they grind. They grind with the most optimal strategies, ignoring fun. And after it I read, how bad it was.
I seen enough posts of people, which farmed different things by using meta strategies from only true guide, which after it complained, that it was boring, dull, soulcrushing.
Because not grinding, usually by relog exploit in their eyes is impossible, because other ways are "worse".
As far as I’m concerned the change strikes a reasonable balance between toning down how some of the medals were just a bit crazy(how many light years of pure distance did the original traveller tier 5 require? it was a little much with over a billion, unless I misremember), and still leaving it harder/requiring more time to get the final tier.
At the rate it was going I would’ve had space combat Elite before tier 1 or 2 of the bounty hunter medal originally, and I spent a fair time in haz res and other pirate hunting activities. Not requiring 40,000 bounties for the highest tier seems quite fair to me.
2,5 millions, similar to final edsm badge "travel distance between milky way and andromeda". And it sounded fair, it showed true dedication to category. Currently you can hit distance for max badge without leaving bubble.
BH badge is...interesting. I'm close to elite I and I had (I think) t3. But it can be created by fact, that game ranks are based on exp. Inara ranks are based on kills.
Oh, and btw, to be fair thats why I liked inara badges. They werent thing, which I grinded (I could let's say mine next 10k stuff in roids for badge, but why if I currently don't enjoy it?), BUT they usually were better than in game ranks (which outside combat base on ONLY credits) and were longer "goal" than in game ranks, which you can max (to last meaningfull rank- elite) in 1 day). Now they still are quite demanding, but it definetely isn't old level "it show true focus and stuff which player X do).
But hey, currently I can grind badge X 4/5 times for some stupid points and total ranking, where top people sit at 6x elite V, and medals XDDD.
Or grind 1 badge 10 times to get new badge, about...badges

Cool opportunity.
