Some interesting arguments for and against.
I do have FOST FOTP and CS at 7, and I would have been happy if they made it an easier farm before I acquired them.
Now? I'm not sure - if that made them significantly easier to farm now, I would feel a bit silly having devoted the time and resource to get those toons, and would have been better served farming gear instead.
This being a game of choices on how you use your scarce resources, changing the farm difficulty midstream will be annoying for many.
Perhaps one way around this is to give something to players that have 7* the toons from these hard farms some type of currency back (shard shop/crystals/whatever), if, and when they decide to shift them to easier locations.
Win-win then, no? People who have got them the long and hard way get some kind of reward, those that did not can now farm them more easily.
