One post that seems to be missing from the forums (and maybe this is not the place for it) is one regarding solid, tested and theorized archtypes.
Obviously we can just rattle them off without any real testing, but I believe it would be more helpful to newer players, and those looking to play seriously (tournaments etc) to consider what archtypes are currently available and where to look for the best cards to make these archtypes work.
The best place to start in our considerations is to think about what the "winning" goals of the game are (aside from having fun). Just off the top of my head, consider these,
-Tanking
-Damage
-Support
-Quest
What heroes fill these roles best (currently) what sphere and what cards within that sphere help these heroes complete the goals.
As you can see, just with these 4 roles placed up there are lines blurring. It is almost certain that some decks can take on multiple roles. But for the sake of learning why not consider the cards BEST suited to accommodate these roles?
But before we get too far into this discussion, how about we outline what these roles are; what their goals should be. Also consider how the roles and the card selection may change based on the number of players. For the sake of theorizing how about we keep our minds in solo, 2, and 3 player games. I think we will find as we move into 3 player considerations, that the roles may get more finite. I think we will also find a better appreciation for the different spheres and how each card may help with completing each task within that "role"
This seems like a good jumping off point for now. I hope to keep this threat updated (with the communities help) with an ongoing dialog of findings. Maybe the discourse here will spawn another thread that can include community "hard facts"
