Yes
I sure hope so, I've earned every shard so far and I'm 50 pts from the top prize. Having this be all RNG based makes it all pure luck to get all the pts needed.
I just don't understand their reasoning. There will be more objectives for everyone to reach the top milestone, so what is the point of making it RNG based? Why even take the extra step?
Could have easily been "per crystal opened" so if you got every shard, you would get the top reward. The possibility of getting every crystal you can based on shards and not get the top reward because you got 10 goblin army too many times is rough on FTP
I'm 220 pts away from that top milestone. This week we only got 2k shards for that week 3 challenge.
