Would it be possible to have a table somewhere that breaks down the drop chances/rarity of Awakening shards in general and specifically for the Powerslave dungeon much like we have for the souls?

So far I've run 7 keys and only gotten 1 awakening shard and if that is how it's supposed to be then the cost in sot and FC to keep buying keys is insanely high. Add to that that the dungeon is still incredibly slow and constantly freezes and to be honest I don't see my Horus being fully awakend any time in the near future.

With regard to the slow downs, I have a suspicion it's when all members of both teams have shields running (I've also noticed this happens with Ferryman a lot, so think his lantern animation may also be a problem)
