I am a huge fan of the game so far.
Im having one major concern tough.
It seems that regarding your party composition, you either have to be a cleric (and maybe a druid once the game releases?) or you have to take Shadowheart with you - otherwise you will have no healer and gonna have a bad time... probably.
Now, the issue that I have with Shadowheart is that you are not able to chose her cleric domain, and they gave her the trickery domain. Which is the worst domain in the book

So there are less customization options there, most of the campaigns will involve an evil trickery domain cleric.
I don't think there are any plans to change that? I would say maybe let us chose the domain, but it fits her personality so I guess no to that...
Maybe more companion options in the future? Or more customization options to the companions are coming? (Im thinking the DoS2 mirror :D)
