This almost sounds to me like they're trying to make exp relevant again, and perhaps future merits will require inordinate amounts of exp. I'm curious to see how this screws over newbs though. Leeching abyssea has always been an option after level 30, but what happens to that when everyone you could possibly hope to leech off of is getting 0 exp per kill even after building kill chain?

And what about aggro? If we're going to start getting less and less exp from enemies, isn't it about time for level 61 enemies to stop aggroing us?
