Decided to buy $20 of gems today to try and roll a 5/8 wg to devo my mino and decided to roll for Dove Keeper and dup heroes instead and hit the jackpot! new problem: who to work on? I have 45k shards saved up right now.
The short answer: Both.
There really isn't any reason to not be sweeping the two of them simultaneously.
If I had to pick only one though, I'd probably go with Dove Keeper, knowing really nothing about her.
I just like new heroes, and I haven't been particularly impressed with Espirita (I do have an Anubis).
