I love this game but I'm stuck doing fates all day. I have OCD and need to get all the trophies. I like grinding but this achievement is keeping me from playing the rest of the game.

Currently 470/1000

I really would like to see this changed or updated to be manageable. Here's what would help:

Change the achievement to 200 or 500 - always thought 1000 was crazy
Make boss fates count is 5x or 10x towards the achievement
Make certain fates quicker, do I have to kill 30+ enemies every time?

Other suggestions welcome. Thanks
