FFC changers used to be combo types... now they are flags. I understand the logic of making them flags, but I preferred them as combo types.
The advantage of making ATT CHG a combo type instead of an FFC flag is that you can set your chosen combo, once, to be an ATT CHG FFC. Then, when you set it up in a quest, you don't have to go to the flag tab and click anything; you just set the location of the FFC, and the new movement for FFCs that pass over it.
As it stands, setting up complicated trap or boss paths now requires an extra three clicks per ATT CHG FFC (click tab, click radio box, click tab). This sounds like not so much, but it adds up over time, and we've already shown its unnecessary.
And, of course, those of us that were tinkering with ATT CHG FFCs before the change was made now have FFCs that don't work AT ALL. Instead, I have ATT CHG FFCs floating around the screen.
