I'm not sure whether this has been suggested before, but I think the game needs team PvP and PvE. That would be nice. I don't think it would be too hard to implement. This would allow for decks where, for example, one player covers while the other player recovers from drawback cards.
Pretty sure it would be hard to develop, but the devs have expressed interest in doing this so it might happen eventually.
I performed a rough feasibility study on this a few weeks ago, since it's certainly something we'd like to do at some point in the future. Interestingly, most of the difficulty lies in building robust interfaces for assembling/managing/disbanding teams. Our next move will likely be further prototyping, to ensure that our vision for how team play would work is actually fun. I don't think we will be doing that in the next few weeks however.
Agreed, you need to beef up the Interface before (or as) you add more features-- or you would just be adding to the frustration of checking/controlling the "miniatures" on the board without say, a zoom (rotate?) function. So to the Thread-starter: no, it is not simple at all-- unless you want Card Hunter to become as "cluttered" as a teenagers' room... 8^S
