I did some testing and not sure if you Guys have seen similar results:
1. account VIP 10+
Did the reset and chose NORMAL mode - I am getting a lot of coins (2x ?) and even more items! (4 different items and 8 different items for every 3rd chest with dragon scales with 12 items for final chest). Most of them are shitty items but got some purples in the process (sadly no hero cards this time).
2. account below VIP10
Same as above, did the reset and selected NORMAL mode... it is as normal as it can be, no change in coins, no change in items.
So, mea culpa - it looks like somethig HAS changed since the last CoF Nightmare event (for NORMAL mode). Can't tell about the Nightmare mode - I simply avoid it because it only frustrates me (I am here to have fun, not yell curses and get angry if you know what I mean).
