We should be able to pick and drop heroes in a particular spot and "pin" them there. So long as they're pinned, movement should be restricted to a small radius around that point (if they're melee) or not at all (if they're ranged/magical).
I would like to see the combined stats of all the current heroes in play. Only stats like gold drop and such...ones that can be combined into single number(crit chance for ex might vary and need not be included).
