I’m sitting on 4000 keys and almost 8,000 gems that I’m waiting very impatiently to spend.
Seriously everybody, get in a good guild!
I’ve stopped saving keys for new kingdoms ever since the keys became different. Spending gems on event keys is enough to max all the important troops from a kingdom.
Mind = blown. Off to spend some keys!
P.s. There is something to be said about spending thousands of keys at once…
yeah a lot of mouse clicking 
Set it and forget it.
