Has anyone noticed a difference in the rewards for elite vs extreme? I did one of each yesterday and an elite today, but nothing popped out at me for differences to explain why I should even bother with extreme. My coins were both 790k, I didn't pay much attention to the extreme survival coins but for elite they are 1500, both gave 14k cultivation runes which I don't need either way and alot of random awakening materials plus some ninja frags.

Please share your experiences so we can find out if there is any reason to do harder difficulties.
