What is your solution to the "problem" then? Let's hear it.
This thread doesn't need to have half a dozen merit sources almost fully dedicated to it, that's not obvious for you?
So what is your solution? You want to take source merits away from them? Why? Less source merits = less received merits = less sMerits in circulation = less chance of lower rank accounts getting merited. It's basic merit-nomics.
If you really feel strongly about it, I guess you'll have to PM theymos, since nobody can change the system except for him -- nor does anybody else want to.
