If you add up the value of the shards' current cost, dropping down to LS Geo TB is MORE than worth it at 40 shards/guild. There is also an omicron that can make KAM shards nearly automatic. And if you really needed help for your guild to get to 40+ successes per TB, I can honestly say that there are a number of people at 50 Shards who would be happy to open up the streaming channels again. The old days with streaming KAM runs were the best.
So while it's not bad to ask CG to change the price of KAM shards to something more commensurate with his current value (and/or to add him to Galactic Bounties or something similar), it's not actually bad value to do LS Geo if KAM is what you need and if you can find a guild (or a group of players who want to form a temporary guild) who have the toons to score 40 shards.
In fact, I calculated the break-even point a while back and it was way under 40 shards. I don't remember what it actually was, but I wouldn't be surprised at high teens or low twenties. Certainly it was below 30.
The long and short is that doing LS Geo is not bad advice so long as CG doesn't introduce new methods of acquisition or change the price. The bad advice is doing ROTE and paying the high costs. So if you're interested in efficiency, either skip KAM until CG makes changes or go for LS Geo. Those are the current best choices.
