I don't care that they earn that rate of personal merit gain really.
Your diversified approach is not really useful when it needs to be applied to one system to combat a method that is generating at that rate there. So if someone is using a farming method, your opposition must be as fast as theirs or you can't overcome it. In some systems that's not horribly hard to do but in others the options for undermining/fortifying may be completely unbalanced and there is simply no reasonable counter to one or the other. That rate of return has not been my experiance to date in doing all the other assorted play. I'm in the top 10% so I'm not exactly bad at it but I'm not pulling 10K an hour at all.
I'm also very sceptical that the bombs are anything other than what the bombers are chuckling about, specifically that they are using the 1T method. When you see 20-30K control points per hour for 5 hours. I'm doubting very hard that this is just diversified play at settlements and pulling power ships and easy going trade. The specifics of how they achieve it or exactly how many are involved are opaque to me but the system traffic is something like 13 in the last 24 hours. So it's not some vast army of randoms just playing the game dumping 170K in 6 hours. So seems as though a wing or two are just PG hauling from external carriers to the station. That's control points too because that's all we can see from the outside.
First: I took a moment to test the one ton method, and it looks like the reports of its demise are premature. Apparently, reports of its demise were due to merits generated by mining, as opposed to high-margin trading.
Second: As a method of generating merits... it isn't
that effective except in very unique circumstances. Under normal conditions, the average player will come out ahead simply by playing the game, and being a bit smart about how they go about it. And there are even better ways of generating merits via buying commodities. I'm generating about 8-10 kilo merits (personal) an hour by playing what I consider "normal." Or around 2000-2500 control credits/hour.
And that's just me messing around, emphasizing fun over effectiveness. I'm pretty sure that if I wanted to suck all the joy of out of this game, and grind away to "win," I could
reliably generate about 8000 (personal) merits every ten minutes for a
single system. Or about 12k control points every hour. Any outgoing merit generation would be icing on the cake.
And
that's as a baseline, without using a carrier, and without using 3rd party sites. Just in my little corner of the Empire, where I've set up shop to test a few theories about fortification. I can
very easily see how, under certain conditions, a player can generate that kind of output you're reporting
without using the one ton method. Why anyone would want to do that to themselves is anyone's guess, but I know from experience such players are out there.
