There was a huge block house complex housing ten thousand families. It was getting really old, the water pipes were leaking and electricity was disturbed daily. Finally the state decided to step in. So they organized a lottery: A single family could move for free to luxurious lakeside mansion, equipped with indoor and outdoor pools and servants included.
Later the state mathematician reviewed statistics and was really happy: There was a notable improvement in average living conditios!
How about notably increasing 4* asc and emblem drop rates everywhere, and roughly halving troop leveling costs, to actually help everyone to progress a little faster? These lottery-things should not give such a huge unfair advantage to some extremely lucky ones.
