Anniversary reward idea

NOOOOOOOOPEEEEE

This recent Featured crystal hasn't had too good of an impression on the fan base, and the last few haven't also been as great. Which got me thinking of something that only seems worthy enough to be an anniversary type thing because of how good it would be.( took a stretch to come this idea I know cause it has nothing to do with the current ones being bad) a Featured Crystal where we choose the pool. It could be just for 5*s or for the 5 and 6* pool.
