Can we finally allow Afterglow and Aftermath to stack?

To make it glow, obviously. Unless they don't?

What you say does make sense... but it's really a trivial thing, afterglows don't really do that much. People do the afterglows because they have to in order to fully complete the item, not because the afterglow stage itself provides amazing super useful effects.

So to me, it seems more silly to make the effort on something that doesn't really matter much in the end.

I appreciate your logic and reasoning here, but that status quo is actually where there is more work/compelxity. It's actually more work to ensure that a party's afterglow effect is overwritten by individual aftermaths. (i.e. a DD will get AM3 up frequently, and overwrite a recently applied afterglow effect that was applied by a shield, for example).

This is also very similar to how Drain/Mantra aren't compatible with each other.
