I am very very new to this game, but already in love.
I would like to expand on this question.
Can the new expansion hero's and classes also be used in the base game?
How about all the new expansion cards?
To clarify, i do not own the game yet. I've ordered it and i expect te receive it in the coming days.
This seems like a game for which i want all the expansions, which would be even better if almost all aspects of an expansion can be used in the base game campaigns.
